Roy Thorsen, whose full name was Roy Thorvald Thorsen, is best known as the longtime husband of classic Hollywood actress Margaret O’Brien, the celebrated child star of Meet Me in St. Louis and many other Golden Age films. Roy and Margaret married on June 8, 1974, and remained together for more than four decades. Away from his wife’s Hollywood fame, Roy built his own career as an electrical engineer and business executive, later developing an interest in restoring Margaret’s historic photographs. The couple also had one daughter, Mara Tolene Thorsen.

Who Was Roy Thorsen?
Roy Thorsen was a professional engineer, business executive, husband, and father.
Most people discover his name because of Margaret O’Brien.
That connection is understandable.
Margaret was one of the most famous child actresses of Hollywood’s Golden Age.
But Roy had a professional story of his own.
He did not enter Hollywood trying to become an actor.
He did not build a career from his wife’s name.
Instead, he worked primarily outside entertainment.
His background included engineering, military education, and business.
This made Roy and Margaret an interesting couple.
One lived much of her life in front of cameras.
The other was comfortable remaining away from them.
Why Is Roy Thorsen Famous?
Roy became publicly known because he married Margaret O’Brien.
Their marriage lasted for decades.
Fans researching Margaret’s personal life eventually find Roy and begin asking questions such as:
Who was Roy Thorsen?
What did Roy Thorsen do for a living?
When did Margaret O’Brien marry him?
Did Roy and Margaret have children?
Was Roy an actor?
How old was Roy Thorsen?
Did Roy work in Hollywood?
What happened to him later?
His relatively private life makes these questions more interesting.
What Was Roy Thorsen’s Full Name?
His full name was Roy Thorvald Thorsen.
He is usually identified simply as Roy Thorsen in discussions of Margaret O’Brien’s family.
The fuller name helps distinguish him from unrelated people who shared the same first and last name.
When Was Roy Thorsen Born?
Roy Thorsen was born on November 13, 1930.
He was born in Brooklyn, New York.
This placed his childhood during a very different period of American life.
He grew up during years shaped by:
The Great Depression.
World War II.
Rapid industrial development.
Major changes in American technology.
Those historical changes also make his later decision to work in engineering understandable.
Where Was Roy Thorsen Born?
Roy was born in Brooklyn, New York.
Brooklyn was already a major urban center when Roy was growing up.
It was home to families from many different cultural and professional backgrounds.
However, specific details about Roy’s childhood home and neighborhood are not necessary to understand his later life.
Who Were Roy Thorsen’s Parents?
Detailed mainstream information about Roy’s parents is limited.
Because Roy was not a movie star, his family background was never documented as heavily as Margaret O’Brien’s.
It would be misleading to fill this gap with unverified names copied from uncertain family-tree websites.
Did Roy Thorsen Have Brothers or Sisters?
His sibling history is also not a major part of his publicly documented biography.
Any brothers, sisters, nieces, or nephews should not be identified without reliable confirmation.
Where Did Roy Thorsen Go to School?
One of the most interesting parts of Roy’s biography is his connection with West Point.
Roy attended the United States Military Academy.
West Point is one of America’s best-known military educational institutions.
Admission is highly competitive.
Students receive a demanding combination of:
Academic training.
Physical training.
Military preparation.
Leadership development.
Graduating from West Point therefore suggests Roy had a disciplined educational background before moving into his civilian career.
Was Roy Thorsen in the Military?
His West Point education gave him a direct military-academic background.
However, a biography should be careful about inventing:
Units.
Deployments.
Combat missions.
Military awards.
Exact service assignments.
Those details should only be stated when reliably documented.
The safest point is that he graduated from West Point before building a career in engineering and business.
Was Roy Thorsen an Engineer?
Yes.
Roy worked as an electrical engineer.
Electrical engineering is a technical field involving electrical systems, electronics, power, communications, control systems, and related technologies.
This profession was very different from Margaret’s acting career.
That contrast is one reason their marriage is interesting.
Margaret came from:
Movie studios.
Stage work.
Television.
Public events.
Roy came from:
Engineering.
Industry.
Business.
Technical problem-solving.
Was Roy Thorsen a Business Executive?
Yes.
His career later included business-executive work, particularly connected with industry.
He has been described as having worked in the steel business after his engineering background.
He therefore built a professional identity that existed independently of Hollywood.
Did Roy Thorsen Work in Hollywood?
Roy did not build a major Hollywood career.
He was not primarily known as:
An actor.
Director.
Movie producer.
Casting agent.
Studio executive.
Talent manager.
His wife happened to be a famous actress.
That did not automatically turn Roy into an entertainment professional.
Was Roy Thorsen an Actor?
No major acting career is associated with Roy.
He sometimes appeared in photographs alongside Margaret at public events.
That is very different from performing in films.
Did Roy Thorsen Appear in Margaret O’Brien’s Movies?
No major acting credits in Margaret’s classic films are associated with Roy.
This would also have been historically unlikely for many of her most famous movies.
Margaret became a major child star decades before she married him.
Who Was Margaret O’Brien?
Margaret O’Brien is an American actress who became one of the most famous child stars of classic Hollywood.
She began appearing in films when she was very young.
Her talent quickly attracted attention.
She became particularly known for her ability to deliver powerful emotional performances despite her young age.
What Is Margaret O’Brien’s Real Name?
Margaret O’Brien was born Angela Maxine O’Brien.
Her professional identity became closely associated with the name Margaret O’Brien after her early film career developed.
TV Guide also identifies Angela Maxine O’Brien as her birth name.
When Was Margaret O’Brien Born?
Margaret O’Brien was born on January 15, 1937.
She was born in San Diego, California.
She entered entertainment very young.
By the 1940s, she was already one of the recognizable children of Hollywood cinema.
How Did Margaret O’Brien Become Famous?
Margaret’s career began during the Golden Age of Hollywood.
Studios at the time often had actors working under long contracts.
Child performers could appear in several films across a short period.
Margaret’s combination of charm, seriousness, and emotional acting made her stand out.
What Movie Made Margaret O’Brien Famous?
Several films contributed to her reputation, but Journey for Margaret became particularly important early in her career.
Later, Meet Me in St. Louis became one of the films most strongly associated with her.
Was Margaret O’Brien in Meet Me in St. Louis?
Yes.
Margaret appeared in the 1944 musical Meet Me in St. Louis.
She played Tootie Smith.
The movie starred Judy Garland.
It became one of the most beloved films of its era.
Margaret’s performance received enormous praise.
Did Margaret O’Brien Win an Oscar?
Margaret received a special Juvenile Academy Award recognizing her work as a child performer.
Her achievements in 1944 were particularly celebrated.
The Juvenile Award was a special honor used during an earlier era of Hollywood to recognize outstanding young performers.
Was Roy Thorsen Married to Margaret During Her Child-Star Years?
No.
This is an important timeline detail.
Margaret was already famous decades before she married Roy.
Her biggest childhood films were made during the 1940s.
Roy and Margaret married in 1974.
That means he met and married an adult woman whose childhood fame was already part of Hollywood history.
Was Margaret O’Brien Still Acting When She Married Roy?
Yes.
Although Margaret’s most famous period came during childhood, her entertainment career did not simply disappear when she became an adult.
She continued performing in:
Television.
Stage productions.
Occasional films.
Public appearances.
Classic-Hollywood events.
Her later career was less intense than her childhood MGM years, but she remained connected with entertainment.
Who Was Margaret O’Brien’s First Husband?
Before Roy, Margaret was married to Harold Allen Jr.
Her first marriage began in 1959 and ended in divorce in 1968.
Roy therefore became her second husband.
Was Roy Thorsen Margaret O’Brien’s Second Husband?
Yes.
Roy was Margaret’s second husband.
Their relationship became much longer than her first marriage.
They married in 1974.
Their marriage lasted more than four decades.
When Did Roy Thorsen Marry Margaret O’Brien?
Roy and Margaret married on June 8, 1974.
This was long after Margaret’s MGM childhood career.
By then, both were mature adults with established life experiences.
How Long Were Roy Thorsen and Margaret O’Brien Married?
Their marriage lasted for nearly 44 years.
They married in June 1974.
Roy died in June 2018.
A marriage lasting more than four decades is notable in any setting.
It becomes especially interesting when one spouse has lived with the unusual pressures of lifelong fame.
Did Roy and Margaret O’Brien Divorce?
No.
Their marriage ended with Roy’s death.
They remained husband and wife for decades.
Did Roy Thorsen and Margaret O’Brien Have Children?
Yes.
They had one daughter together.
Her name is Mara Tolene Thorsen.
Who Is Mara Tolene Thorsen?
Mara Tolene Thorsen is the daughter of Roy Thorsen and Margaret O’Brien.
She was born in 1977 according to biographical records.
Unlike her mother, Mara did not become internationally famous as a childhood movie star.
That gave her an opportunity to build a much more private adult life.
Is Mara Thorsen Margaret O’Brien’s Daughter?
Yes.
Mara is Margaret O’Brien’s daughter with Roy Thorsen.
She is also Margaret’s publicly known child.
Was Mara Thorsen an Actress?
No major mainstream acting career defines Mara publicly.
Some biographical sources describe her professional interests in academic or sociological areas rather than Hollywood acting.
She should not automatically be described as an actress simply because her mother was one.
Did Roy Thorsen Have More Children?
No additional children should be confidently assigned to Roy without strong documentation.
His best-known child is Mara.
What Was Roy Thorsen Like as a Father?
Only Mara and people close to the family could answer that properly.
A public biography should not invent descriptions such as:
Strict.
Perfect.
Distant.
Protective.
Funny.
Traditional.
Those are personal judgments.
What can be said is that Roy and Margaret raised their daughter largely outside the intense child-star publicity Margaret herself had experienced.
Did Roy Thorsen Attend Hollywood Events With Margaret?
Yes.
Archival photographs show Roy attending entertainment events with Margaret.
In some photographs, their daughter Mara also appeared with them.
The family attended various Hollywood social occasions during the 1970s and later years.
Was Roy Comfortable Around Hollywood?
He appeared publicly with Margaret at selected events.
However, he never turned those appearances into a celebrity career.
That suggests he was comfortable supporting his wife publicly while keeping his own identity separate.
Was Roy Thorsen a Celebrity Husband?
In one sense, yes.
He was married to a famous actress.
But “celebrity husband” does not fully describe him.
Roy had already developed education and professional skills that had nothing to do with Margaret’s fame.
He was:
A West Point graduate.
An electrical engineer.
A business executive.
A husband.
A father.
Later, a photo-restoration enthusiast.
Did Roy Thorsen Retire?
Yes.
Roy reportedly retired around 2000.
Retirement gave him more time for personal interests.
One of those interests became unexpectedly connected with Margaret’s long Hollywood career.
What Did Roy Thorsen Do After Retirement?
Roy became interested in restoring old photographs.
This was particularly useful because Margaret possessed decades of photographs connected with her acting career.
Some of those images had:
Faded.
Been damaged.
Aged.
Lost visual quality.
Roy learned digital techniques that could help preserve them.
Why Did Roy Thorsen Start Restoring Photographs?
Roy explained that after he retired, Margaret pointed out that many of her older photographs had become faded or damaged.
He told her computer software could potentially restore them.
Margaret encouraged him to learn how to do it.
Roy did exactly that and turned photo restoration into a serious interest.
Did Roy Restore Margaret O’Brien’s Old Hollywood Photos?
Yes.
This became one of the most charming details of their later life together.
Margaret had an enormous visual history.
She had been photographed:
As a young MGM actress.
On movie sets.
At premieres.
With other actors.
For publicity portraits.
At award events.
Many of those images were decades old.
Roy’s technical background made digital restoration a natural hobby.
Why Was Photo Restoration Important?
Old entertainment photographs can deteriorate.
They may develop:
Scratches.
Color changes.
Fading.
Tears.
Dust marks.
Missing sections.
Digital restoration can help repair damage while preserving the original image.
For someone like Margaret O’Brien, those photographs were not just family memories.
They were also pieces of Hollywood history.
Did Roy Sell Restored Photographs?
Roy’s interest grew from preserving Margaret’s old photographs.
His work showed how modern technology could protect historical images.
However, it would be misleading to exaggerate the hobby into a giant commercial photography company without stronger evidence.
Was Roy Thorsen a Photographer?
Photo restoration and photography are related but different.
Roy became associated with restoring photographs digitally.
That does not automatically mean he built a professional career as a photographer taking new images.
Did Roy’s Engineering Background Help With Photo Restoration?
It may have made technical software easier for him to approach.
Electrical engineers are often comfortable with technology and problem-solving.
However, the exact learning process should not be invented.
What is clear is that Roy became skilled enough to discuss his restoration work publicly.
Did Roy Thorsen Give Interviews?
He rarely developed a public-media identity.
However, his discussion of photograph restoration gives a rare glimpse into his own voice and interests.
That makes it particularly valuable when understanding who he was beyond Margaret’s husband.
Was Roy Thorsen Private?
Yes.
Compared with Margaret, Roy lived a much less public life.
He did not become:
A reality-TV personality.
Hollywood gossip figure.
Regular talk-show guest.
Celebrity memoir writer.
Social-media influencer.
He generally remained outside the spotlight.
Why Was Roy Thorsen So Private?
Because fame was not his profession.
Margaret had been publicly recognized since childhood.
Actors often have to:
Attend events.
Give interviews.
Promote projects.
Meet fans.
Pose for photographs.
Roy’s engineering and executive careers had very different requirements.
That allowed him to preserve a more ordinary public identity.
Did Roy Thorsen Benefit From Margaret O’Brien’s Fame?
Marriage to a famous actress naturally brought social opportunities and public recognition.
However, that does not mean Roy built his livelihood around her celebrity.
His engineering and business careers gave him his own professional identity.
Did Roy Manage Margaret O’Brien?
There is no major evidence showing Roy served as Margaret’s formal professional manager.
A supportive husband and a talent manager are different things.
He should not automatically be described as her:
Agent.
Manager.
Publicist.
Producer.
Business representative.
Did Roy Control Margaret O’Brien’s Career?
No evidence supports that kind of claim.
Margaret had already spent decades in entertainment before they married.
She had her own professional experience.
Did Roy Help Preserve Margaret’s Legacy?
In one meaningful way, yes.
His work restoring her historic photographs helped protect visual memories from her career.
That is different from controlling her films or acting rights.
It was a personal contribution to preserving family and entertainment history.
Was Roy Thorsen Rich?
Roy built a professional career as an engineer and executive.
Margaret also had a long entertainment career.
That may have provided the household with financial stability.
However, vague claims about Roy being extremely wealthy should be avoided.
What Was Roy Thorsen’s Net Worth?
Roy’s personal net worth was never independently verified in a reliable public way.
Online biography sites may publish exact figures.
Those numbers should be treated carefully.
A real calculation would require information about:
Salary.
Retirement assets.
Property.
Investments.
Savings.
Debt.
Business holdings.
Those details were private.
Was Margaret O’Brien’s Money Roy Thorsen’s Money?
Marriage can involve shared finances.
However, spouses can also have separate professional earnings, investments, and property.
It would be inaccurate to simply assign all of Margaret’s acting earnings to Roy.
Did Roy Receive Money From Margaret O’Brien’s Movies?
Being married to an actress does not automatically give a spouse ownership of her movie contracts or residuals.
Any family financial arrangements were private.
Did Roy Own Margaret O’Brien’s Oscar?
No.
Margaret’s Juvenile Academy Award belonged to her and became part of her remarkable Hollywood history.
Roy should not be described as its owner simply because they were married.
What Happened to Margaret O’Brien’s Oscar?
Margaret’s Juvenile Oscar famously went missing for many years.
It had disappeared after being taken from the family’s possession.
Decades later, it was recovered after turning up in the collectibles market.
The story became one of the unusual chapters of Margaret’s Hollywood history.
Was Roy Involved in Finding Margaret’s Oscar?
No major claim should be made that Roy personally discovered the award unless clearly documented.
The Oscar’s recovery involved circumstances separate from his photograph-restoration hobby.
Did Roy Thorsen Know Other Classic Hollywood Stars?
As Margaret’s husband, Roy had opportunities to attend events with figures from classic entertainment.
However, being photographed near another celebrity does not automatically mean they were close friends.
Did Roy Know Judy Garland?
Margaret worked with Judy Garland when she was a child.
Roy married Margaret decades later.
There is no reason to assume Roy had a meaningful personal relationship with Garland.
Judy Garland died several years before Roy and Margaret married.
Did Roy Know Elizabeth Taylor?
Margaret belonged to the same broader classic-Hollywood generation as many famous stars.
Roy may have encountered well-known entertainment figures through events.
Again, possible contact should not be turned into invented friendship.
Did Roy Thorsen Know Mickey Rooney?
The same caution applies.
Roy’s wife had long-standing Hollywood connections.
His own friendships should not be guessed from her film history.
How Did Roy Handle Being Married to a Former Child Star?
Only Roy could fully answer that.
Margaret had experienced fame from an extremely young age.
That can create unusual challenges.
A famous child actor may spend adulthood living with:
Public recognition.
Fans remembering childhood roles.
Questions about old films.
Constant nostalgia.
Press interest.
Roy appears to have accepted that history without trying to compete with it publicly.
Did Roy and Margaret Have a Stable Marriage?
Their marriage lasted for more than four decades.
That length itself shows considerable continuity.
However, no outsider should pretend to know every private detail.
Long marriages can include:
Love.
Challenges.
Arguments.
Compromise.
Health problems.
Family responsibilities.
Shared memories.
The important public fact is that the marriage continued until Roy’s death.
Did Roy and Margaret Ever Separate?
No widely reported permanent separation became part of their marriage history.
They continued to be publicly identified as husband and wife.
Was Roy Margaret O’Brien’s Longest Marriage?
Yes.
Her marriage to Roy lasted much longer than her first marriage.
Roy became her companion for most of her later adult life.
When Did Roy Thorsen Die?
Roy Thorsen died on June 4, 2018, just days before what would have been the couple’s 44th wedding anniversary.
How Old Was Roy Thorsen When He Died?
Based on the reported November 13, 1930 birth date and June 4, 2018 death date, Roy was 87 years old.
He would have turned 88 later that year.
What Was Roy Thorsen’s Cause of Death?
Detailed reliable mainstream information about his exact cause of death is limited.
It would be inappropriate to invent a medical condition.
When health information is not clearly established, the safest answer is simply that Roy died in 2018 at age 87.
How Did Roy Thorsen’s Death Affect Margaret O’Brien?
Margaret lost her husband of nearly 44 years.
That alone explains the importance of the loss.
No biography should invent:
Her final conversation with Roy.
Her private grief.
Her exact emotional state.
Medical-room details.
Personal family conversations.
Grief belongs to the family.
Did Margaret O’Brien Remarry After Roy Thorsen Died?
No later marriage has become a major established part of Margaret’s public biography.
Roy remained her longtime second husband.
Was Roy Thorsen Alive During Margaret O’Brien’s Later Career?
Yes.
Roy saw Margaret continue to receive recognition for her enormous contribution to classic cinema.
Her childhood films remained popular long after their original release.
New generations continued discovering her work.
Did Roy Attend Classic Hollywood Events With Margaret?
Yes.
Roy appeared with Margaret at various public events during their marriage.
Historical photographs show them together at Hollywood social occasions.
Did Their Daughter Attend Events Too?
Yes.
Archival images also show Roy, Margaret, and Mara attending some events together when Mara was young.
These images offer rare glimpses of the family together.
Was Roy Thorsen on Social Media?
Roy’s adult life began long before social media existed.
By the time Instagram, Facebook, and similar platforms became major parts of celebrity culture, Roy was already an older private individual.
He never became known as a social-media personality.
Did Roy Have Instagram?
There is no major public Instagram identity associated with him.
Accounts using the same name should not automatically be treated as belonging to Margaret O’Brien’s husband.
Why Are There Different Roy Thorsens Online?
Roy Thorsen is not a completely unique name.
Other people have carried it.
This can create confusion in:
Obituaries.
Social-media accounts.
Business listings.
Family trees.
Professional databases.
A different Roy Thorsen should not be accidentally mixed with Margaret O’Brien’s husband.
Is Roy Thorsen the Same Person as Every Roy Thorsen Obituary Online?
No.
This is especially important.
There have been unrelated people named Roy Thorsen.
A death notice from a different state, with a different spouse or children, should not be attached to Margaret O’Brien’s husband.
Identity matching matters.
Is Roy Thorsen Related to Other Famous Thorsens?
No family relationship should be assumed simply from the surname.
Thorsen is a surname found in many unrelated families.
What Makes Roy Thorsen’s Story Interesting?
The contrast between his life and Margaret’s.
Margaret began working in Hollywood when she was very young.
She became famous before most children even understand what a career is.
Roy grew up in Brooklyn.
He attended West Point.
He became an engineer.
He moved into business.
Then their lives came together.
They married in 1974.
Instead of using the marriage to become famous himself, Roy continued living relatively privately.
They became parents.
They attended occasional Hollywood events.
Roy eventually retired.
Then he used modern technology to help preserve images from Margaret’s old Hollywood life.
That is a surprisingly fitting ending to his professional story.
An engineer became the person restoring photographs from a classic actress’s childhood career.
Why Is Roy Thorsen More Than Margaret O’Brien’s Husband?
Because marriage was only one part of his life.
He had already built:
An education.
Technical skills.
A professional career.
Leadership experience.
Personal interests.
Margaret’s fame explains why the public knows his name.
It does not mean he existed only in relation to her.
Did Roy Thorsen Use Margaret O’Brien’s Fame?
There is little evidence that he tried to turn the marriage into his own celebrity career.
He did not become known for:
Reality television.
Celebrity gossip.
Tell-all books.
Hollywood acting.
Public feuds.
That low profile is one of the clearest characteristics of his public story.
Why Do People Search for Roy Thorsen Today?
Interest usually begins with classic Hollywood.
Someone watches Meet Me in St. Louis.
They notice Margaret O’Brien.
They search her life.
Then they discover her husband.
That leads to:
Who was Roy Thorsen?
What did he do?
Was he an actor?
Did he and Margaret have children?
How long were they married?
When did he die?
What happened to their daughter?
Fans of classic film naturally become interested in the real lives behind famous performances.
What Information About Roy Thorsen Is Often Confused Online?
Several areas require care:
His identity.
His death date.
His professional career.
Other men named Roy Thorsen.
His daughter’s biography.
Exact military service.
Financial information.
Internet biographies often become unreliable when writers copy unrelated records simply because a name matches.
Was Roy Thorsen a Hollywood Millionaire?
No reliable evidence supports describing him in those terms.
He had a successful professional career and was married to a famous actress.
That is not enough to assign a specific wealth category.
Did Roy Thorsen Live in Beverly Hills?
The family appeared at events in Beverly Hills.
That does not mean an event location was necessarily their permanent residence.
Exact home addresses should remain private.
Where Did Roy Thorsen Live With Margaret O’Brien?
The couple lived in California during much of their married life and had strong connections with the Los Angeles entertainment community.
However, exact private residential details are unnecessary.
Did Roy Thorsen Have a Hobby After Retirement?
Yes.
His photo-restoration work became one of the most clearly documented interests from his later years.
It combined:
Technology.
History.
Art.
Family memories.
That made it much more than a random hobby.
Why Were Margaret O’Brien’s Photos Worth Preserving?
Margaret’s career began during one of Hollywood’s most important eras.
Her photographs can show:
Studio life.
Costumes.
Actors.
Publicity methods.
Award ceremonies.
Film history.
Child stardom.
Preserving them helps maintain a record of classic cinema.
Did Roy Understand the Importance of Margaret’s Career?
His effort to restore her photographs strongly suggests he understood the value of preserving those memories.
Still, exact private feelings should not be invented.
What Was Roy Thorsen’s Greatest Public Contribution?
He was not someone trying to build a public legacy.
His strongest publicly documented achievements came through his professional career and later his work preserving Margaret’s photographs.
But his family may remember completely different things.
Public achievements and personal importance are not always the same.
What Is Roy Thorsen Remembered for Today?
Roy is remembered primarily as:
Margaret O’Brien’s longtime husband.
A West Point graduate.
An electrical engineer.
A business executive.
Mara Thorsen’s father.
A private man who supported a famous spouse.
Someone who helped restore and preserve Margaret’s old photographs.
Why Should Roy Thorsen’s Story Be Told Carefully?
Because he was not a full-time celebrity.
That means the public record is smaller.
When reliable information is limited, writers sometimes fill gaps with guesses.
That can create false biographies.
A better approach is to separate what is known from what remains private.
Final Thoughts
Roy Thorsen is best remembered publicly as the longtime husband of Margaret O’Brien, but his life had a clear identity beyond Hollywood.
Born in Brooklyn in 1930, Roy followed a path very different from Margaret’s.
He attended West Point.
He entered a technical profession.
He became an electrical engineer.
He later worked in business and industry.
Margaret’s childhood could hardly have been more different.
She entered movies when she was very young.
By the 1940s, she had become one of MGM’s most celebrated child performers.
Films such as Journey for Margaret and Meet Me in St. Louis made her a major star.
She received a Juvenile Academy Award for her work.
Roy and Margaret did not meet as children growing up around the same world.
Their lives came together much later.
Margaret had already experienced decades of fame.
She had also been through an earlier marriage to Harold Allen Jr.
Then, on June 8, 1974, she married Roy Thorsen.
The marriage became the lasting relationship of her adult life.
Together, they had one daughter, Mara Tolene Thorsen.
The family sometimes appeared together at Hollywood events, but Roy never attempted to become a major celebrity.
He continued to be known primarily through engineering and business.
That independence made their relationship unusual.
Margaret could remain the actress.
Roy could remain the engineer and executive.
Years passed.
Margaret’s childhood films became classics.
People who had watched her as children grew old.
Then new generations discovered the same movies.
Roy eventually retired around 2000.
Instead of completely leaving technical interests behind, he found a new use for them.
Margaret had many old photographs from her career.
Some had faded or become damaged.
Roy learned computer-based restoration techniques and began repairing them digitally.
That hobby brought his technical world and Margaret’s Hollywood world together in a surprisingly meaningful way.
The engineer helped preserve the actress’s history.
Roy and Margaret remained married for nearly 44 years.
Their relationship ended only when Roy died in June 2018 at age 87.
His death closed a major chapter of Margaret O’Brien’s personal life.
Several parts of Roy’s story still deserve privacy.
His family relationships outside Margaret and Mara were never heavily documented.
His finances were private.
No reliable independent net-worth figure should be treated as fact.
His exact military assignments should not be invented from his West Point education.
His medical history should also not be guessed.
What remains clear is more than enough.
Roy Thorsen lived most of his life outside celebrity culture even while being married to someone who had been famous almost from childhood.
He built his own career.
He became a husband and father.
He shared more than four decades with Margaret.
And in retirement, he found a deeply personal way to help protect pieces of her Hollywood past.
Roy Thorvald Thorsen was Margaret O’Brien’s longtime husband, a West Point graduate, electrical engineer, business executive, and father of their daughter Mara Tolene Thorsen. Married to the classic Hollywood actress from 1974 until his death in 2018, Roy remained largely outside the spotlight while sharing nearly 44 years with one of cinema’s most celebrated former child stars.
