Glynn Daly is a name that often appears beside some of American television’s best-known creative figures, yet she has spent much of her own life away from fame. Also publicly known as Mary Glynn Daly and Glynnis Snow, Glynn Daly is the daughter of actor James Daly, the sister of actors Tyne Daly and Tim Daly, and the wife of the late television composer Mark Snow. Unlike several members of her famous family, she chose a much more private path.

Who Is Glynn Daly?
Glynn Daly comes from a family with deep roots in American acting and television.
Her father, James Daly, built a respected career on stage and screen. He became especially well known for playing Dr. Paul Lochner on the television drama Medical Center. James Daly and actress Mary Hope Newell Daly had four children.
Those children were Tyne Daly, Glynn Daly, Pegeen Michael Daly and Tim Daly.
Two of them became major actors.
Tyne Daly built a long career in television, film and theater. She became especially famous through Cagney & Lacey.
Tim Daly also became a familiar television face through projects such as Wings, Private Practice and Madam Secretary.
Glynn took a different route.
She remained connected to the creative world but did not build the same kind of public celebrity career as Tyne and Tim. That difference is one reason people continue searching for her today.
Is Glynn Daly Also Known as Glynnis Snow?
Yes.
This is one of the biggest sources of confusion surrounding her online.
Reliable reports refer to her using several forms of her name, including Mary Glynn Daly, Glynn Daly and Glynnis Snow.
The Washington Post reported that composer Mark Snow married Mary Glynn Daly, known as Glynnis, while PEOPLE refers to Tim Daly’s sister as Glynnis Snow. Tim Daly’s biographical information also identifies one of his sisters as Mary Glynn.
Therefore, searches for Glynn Daly and Glynnis Snow generally point to the same person.
That is important because some online biographies treat the names as though they belong to different women. Reliable information does not support that idea.
What Was Glynn Daly’s Childhood Like?
Glynn grew up in a family where acting was part of normal life.
PEOPLE reports that James and Hope Daly raised their four children in Rockland County, New York. Their father was strongly involved in the theater world, and creative work surrounded the family from an early age.
It was not simply a household where celebrity mattered.
Tim Daly has described acting as something his father treated seriously and with respect. That attitude appears to have shaped the family.
Tyne followed her father into acting and eventually became one of the most recognized members of the Daly family.
Tim followed as well.
Glynn remained closer to the private side of the entertainment world.
Her story therefore shows another side of growing up inside a successful Hollywood family. Being surrounded by actors does not automatically mean every family member wants to become a public star.
Who Are Glynn Daly’s Parents?
Glynn’s father was James Firman Daly, born in 1918.
He worked professionally as an actor from the 1940s until his death in 1978. His career included television, film and Broadway work. His best-known television roles included Medical Center and Twelve O’Clock High.
Her mother was Mary Hope Newell Daly, often called Hope Newell.
She also had connections with acting and stage work.
Together, James and Hope created an artistic family environment that later produced several successful performers.
James Daly died in July 1978 at age 59.
His influence, however, continued through his children.
Is Glynn Daly Related to Tyne Daly?
Yes. Tyne Daly is Glynn Daly’s sister.
Tyne is perhaps the most decorated performer in the family.
She became widely known for playing Mary Beth Lacey in Cagney & Lacey. Her career later included major television and theater roles.
Glynn and Tyne may have lived very different professional lives, but they belong to the same close creative family.
PEOPLE has also published images of the Daly siblings together, showing that Glynn has occasionally appeared publicly alongside her famous relatives.
Is Glynn Daly Tim Daly’s Sister?
Yes.
Actor Tim Daly is Glynn’s younger brother.
Born in New York City in 1956, Tim became known for playing Joe Hackett on Wings. He later appeared in The Sopranos, Private Practice and Madam Secretary, while also becoming well known as the voice of Superman in animated productions.
Tim was the only son among the four Daly children.
His three sisters were Tyne, Glynn and Pegeen.
Because Tim and Tyne became so famous, many people discover Glynn while researching their family.
Who Was Glynn Daly’s Sister Pegeen Daly?
Pegeen Michael Daly was another member of the Daly family who lived a less public life than Tyne or Tim.
PEOPLE reports that Pegeen died in 2019 after dealing with serious health problems.
After her death, Tyne shared a personal tribute that Tim later posted publicly. The family message showed how close the siblings remained.
It specifically referred to sister Glynn, brother Tim and their extended family as people who would deeply miss Pegeen.
This gives readers a rare look at Glynn not as a connection to celebrities, but simply as a sister within a close family.
Who Was Glynn Daly’s Husband Mark Snow?
Glynn Daly was married to Mark Snow, one of television’s most recognizable composers.
Snow was born Martin Fulterman in 1946.
He studied music and later built a major career composing for television and film.
His credits included The X-Files, Smallville, Ghost Whisperer, Blue Bloods, Millennium, Hart to Hart and several other productions.
However, one piece of music made him especially famous.
That was the haunting theme from The X-Files.
Even people who never watched every episode of the show may recognize its mysterious sound.
Snow’s career earned him numerous major award nominations and made him an important figure in television music.
When Did Glynn Daly and Mark Snow Get Married?
The safest date supported by strong reporting is 1967.
The Washington Post reported after Mark Snow’s death that he married Mary Glynn Daly, known as Glynnis, in 1967.
Some entertainment databases show different marriage dates, which has caused confusion online.
For example, certain listings refer to later dates or separate marriage records. Because these databases do not fully agree, they should not be treated as stronger evidence than established news reporting.
For an accurate biography, it is better to say that reliable published reporting identifies 1967 as the year Glynn and Mark married.
The couple went on to build a family while Snow’s music career expanded.
Did Glynn Daly and Mark Snow Have Children?
Yes.
Glynn and Mark had three daughters.
The Washington Post identified their daughters as Sarah, Nora and Megan when reporting on Snow’s death. The report also said the family included four grandsons.
PEOPLE similarly confirms that Glynnis and Mark shared three daughters.
Very little reliable public information is available about the daughters’ private lives.
That privacy should be respected.
Being part of a famous entertainment family does not automatically make someone’s children public celebrities.
Did Glynn Daly Have Her Own Entertainment Career?
This question needs a careful answer.
Some online biographies describe Glynn as an actress or theater performer. However, strong public sources do not provide enough evidence for a large professional acting career comparable with Tyne Daly or Tim Daly.
PEOPLE specifically describes Glynnis as someone who did not seek the Hollywood spotlight.
However, Glynn does have at least one important verified creative credit.
The Television Academy lists Glynn Snow alongside Mark Snow as a nominee for Outstanding Achievement in Music and Lyrics for the 1990 television production The Lost Capone.
That is a much stronger fact than simply calling her a private celebrity relative.
It shows that Glynn had her own documented creative involvement in television music.
Was Glynn Daly Nominated for an Emmy?
Yes.
This is one of the most interesting facts about her.
The Television Academy’s official records show Mark Snow and Glynn Snow as nominees in the 1991 category for Outstanding Achievement in Music and Lyrics for The Lost Capone.
They did not win the category.
Still, an Emmy nomination is a meaningful professional achievement.
This detail is sometimes missed because Glynn never built a highly public entertainment profile.
It also shows why describing her only as “Tim Daly’s sister” or “Mark Snow’s wife” does not tell the whole story.
She had a verified creative credit of her own.
Did Glynn Daly Help With The X-Files Music?
There is an interesting connection.
PEOPLE reports that Mark Snow once discussed his wife’s ability to whistle when talking about the famous sound associated with The X-Files. The account describes Glynnis offering to add her own whistling.
The story adds a personal touch to one of television’s most famous themes.
Still, it is important not to turn that story into an exaggerated claim that Glynn alone created the X-Files theme.
Mark Snow is officially recognized as its composer.
Glynn’s connection is better understood as part of the creative and personal environment around his work.
Why Did Glynn Daly Stay Away From Hollywood Fame?
There is no verified public interview in which Glynn gives one clear reason.
So it would be wrong to invent an explanation.
What we can say is that her public life has been much quieter than those of Tyne and Tim.
She has appeared at events with Mark Snow and family members, but she did not build the constant media presence usually associated with Hollywood actors.
That choice has also protected much of her personal life.
Only limited details about her education, daily life and personal interests have entered reliable public records.
In an era where celebrity families can become brands of their own, Glynn’s privacy stands out.
What Happened to Mark Snow?
Mark Snow died in July 2025 at age 78.
Reliable reports said he died at his home in Washington, Connecticut, after suffering from myelodysplastic syndrome, a rare blood disorder.
His death brought renewed attention to his remarkable career.
It also led major publications to mention Glynnis and their daughters while looking back at his life.
PEOPLE describes Glynn as his wife and refers to the couple’s three daughters.
As of the reliable information available publicly, Glynn should therefore be described as Mark Snow’s widow, not simply as his current wife without context.
What Is Glynn Daly’s Age?
Glynn Daly’s exact age is not reliably confirmed in major public sources.
Many websites publish estimated ages or birth years.
Those figures should be treated carefully.
Neither PEOPLE’s detailed look at the Daly siblings nor the strongest biographical sources reviewed here provide a confirmed date of birth for Glynn.
For that reason, giving a precise age would create false certainty.
A responsible biography should simply say that her birth date has not been clearly established through reliable public reporting.
When Is Glynn Daly’s Birthday?
Her exact birthday is also not reliably documented.
This is another case where smaller biography sites may publish specific information without explaining where it came from.
Without a reliable record, repeating such a date can spread incorrect information.
Therefore, Glynn Daly’s birthday should be listed as not publicly confirmed.
What Is Glynn Daly’s Net Worth?
There is no trustworthy public estimate of Glynn Daly’s personal net worth.
Celebrity websites often attach net-worth figures to people connected with famous families.
However, those numbers may be guesses rather than verified financial information.
Glynn has kept her finances private.
Mark Snow had a long and successful composing career, but that does not allow us to calculate Glynn’s personal wealth.
Income, property, investments, royalties, trusts and estate arrangements are private financial matters unless reliable records make them public.
Any precise Glynn Daly net worth figure should therefore be treated with caution.
Where Does Glynn Daly Live?
Reliable reporting has connected Glynn and Mark Snow with Connecticut.
Mark Snow died at his home in Washington, Connecticut, in 2025. Other public records have also connected Mark and Glynnis Snow with community activity in that area.
However, Glynn’s current private residence should not be guessed or presented in unnecessary detail.
General location information is enough for a public biography.
Exact addresses and other private location details are not needed.
Why Do People Search for Glynn Daly Today?
Interest in Glynn comes from several directions.
Some people discover her while reading about Tim Daly.
Others search for her because of Tyne Daly.
Fans of The X-Files may find her name while researching Mark Snow.
Then there is her own Emmy-nominated work, which adds another interesting piece to her story.
Together, these connections make Glynn a fascinating example of someone who lived close to Hollywood fame without making celebrity her main public identity.
What Makes Glynn Daly Different From Her Famous Siblings?
The contrast is simple.
Tyne and Tim built careers in front of cameras and audiences.
Glynn largely stayed outside that world.
Yet she was never completely separated from the creative industry.
She grew up with an accomplished actor as her father. She married one of television’s best-known composers. She received a verified Emmy nomination with Mark Snow for The Lost Capone.
Her story is therefore not one of avoiding creativity.
It is more about having a creative life without needing constant fame.
What Is Glynn Daly Best Known For?
Most people know Glynn for four main reasons.
She is the daughter of James Daly.
She is the sister of Tyne Daly and Tim Daly.
She was the longtime wife of composer Mark Snow.
Finally, she earned an Emmy nomination under the name Glynn Snow for her work with Mark on The Lost Capone.
Those facts provide a much clearer picture than many short celebrity biographies online.
Final Thoughts
Glynn Daly belongs to one of America’s notable entertainment families, but her life shows that fame can take many forms.
Her father, James Daly, became a respected television and stage actor. Her siblings Tyne and Tim built major acting careers. Her husband, Mark Snow, created music heard by millions of television viewers.
Glynn chose a quieter public life.
Still, she was more than a famous person’s sister or wife. Official Television Academy records show that Glynn Snow shared an Emmy nomination with Mark Snow for The Lost Capone.
That verified achievement adds an important layer to her story.
At the same time, many details about her remain private. Her exact birth date, age and personal net worth are not reliably confirmed. Rather than filling those gaps with guesses, an accurate biography should respect them.
That privacy may actually be one of the most defining parts of Glynn Daly’s story.
