Glynn Daly is best known as the sister of actors Tyne Daly and Tim Daly and the wife of the late composer Mark Snow. The story of Glynn Daly and Mark Snow runs through a famous acting family, a husband whose eerie theme music for The X-Files became one of television’s best-known tunes, and three daughters. If you’re asking who is Glynn Daly outside that outline, the public record is thin, and the pages offering a precise Glynn Daly age or Glynn Daly net worth rarely say where the numbers came from.
She’s searched far more often since July 2025, when news of Snow’s death named his wife and sent readers looking for her. What they find is a pile of near-identical pages. Some call her a theatre actress who “chose privacy over stardom”. Others credit her with mentorship and activism without naming a single project. One page even carries a leftover heading about a different woman’s father, which is what happens when a template gets reused without anyone reading it.
This profile is deliberately shorter on colour and longer on caveats. It sticks to what Wikipedia, genealogy records and published obituaries say, flags everything else as repeated rather than confirmed, and leaves out her daughters’ names, her grandchildren and her address.

The first six rows are well supported. From “marriage year” down, it’s mostly repetition or silence.
Who Is Glynn Daly?
A private woman from a well-known American acting family, known almost entirely through her relatives. Wikipedia’s entries for her brother and sister name her as Mary Glynn, wife of Mark Snow, and the entry for her father lists two other children, daughters Mary Glynn and Pegeen Michael.
Mark Snow’s own Wikipedia article says he was married to Glynnis Daly and had three children, and that through the marriage he was brother-in-law to Tyne and Tim Daly. Those entries are the firmest foundation anyone has. I found no screen credits under her name, no published interview and no verified social media account.
Why Is Glynn Daly Famous?
She isn’t, quite. She’s searched for because of the people around her.
Her father, James Daly, was a stage, film and television actor, best known as Paul Lochner in the hospital drama Medical Center. Her sister Tyne won a Tony Award in 1990 for the musical Gypsy and played Mary Beth Lacey in Cagney & Lacey. Her brother Tim starred in the sitcom Wings. Her husband scored more than 200 episodes of The X-Files and earned 15 Emmy nominations, according to Variety’s obituary as summarised by other outlets. With a family like that, readers naturally wonder about the member they haven’t heard of.
Glynn Daly’s Parents: James Daly and Hope Newell
Her father was James Daly, who lived from October 23, 1918 to July 3, 1978, according to Wikipedia. Her mother was the actress Hope Newell, whom Tim Daly’s Wikipedia entry gives as 1921 to 2009. Genealogy records put their marriage in 1942, and a Google summary of James Daly lists it as ending in 1965.
Wikipedia says the couple had four children. Several lifestyle pages go further and describe a childhood “soaked in theatre”. That’s a reasonable guess for a family like this one, but it’s a guess, and none of those pages cites a source for it.
Glynn Daly’s Siblings: Tyne, Tim and Pegeen Michael
She has two sisters and a brother. Tyne Daly, born February 21, 1946, is the actress. Tim Daly, born March 1, 1956, is described by Wikipedia as the only son and youngest of the four children. The fourth sibling is Pegeen Michael Daly, who barely appears in any coverage.
Those two birth dates matter later, because they’re the only anchors anyone has for estimating Glynn’s age. Tyne and Tim have said plenty in public over the years. Glynn hasn’t, as far as I can find.
Glynn Daly and Mark Snow: The Marriage
She married Mark Snow, the composer born Martin Fulterman on August 26, 1946. He’s best known for the main theme of The X-Files, which he scored for the show’s original run from 1993 to 2001, and he also composed for shows like Hart to Hart, Smallville and Blue Bloods.
They were still married when he died. Multiple outlets, including Variety’s report as repeated by Newsweek and TheWrap, said he died at home in Connecticut on Friday, July 4, 2025, aged 78, and that he was survived by his wife Glynnis, three daughters and grandchildren. Wikipedia places his death in Washington, Connecticut. A cause hasn’t been confirmed in the reports I read, so I haven’t repeated one.
When Did Glynn Daly Marry Mark Snow?
Nobody agrees. A MyHeritage biographical summary lists the marriage as 1967. Another profile says 1980. A year can’t be both, and neither page cites a marriage record or an interview.
Here’s the thing: 1967 would have made them very young, and 1980 would sit oddly with daughters said to be born around 1971 on that same genealogy summary. I can’t resolve it, and I’d rather leave the cell as “Not publicly confirmed” than pick the tidier story.
Glynn Daly’s Children
Three daughters, according to Wikipedia and the obituaries. One genealogy summary and a few lifestyle pages name them. They’re adults with their own lives, and nothing about this article requires their names, so I haven’t repeated them.
Obituaries also mention grandchildren, and one outlet said four. That’s the extent of what I’d say. If a page offers ages, schools or addresses for any of them, treat it with suspicion.
What Does Glynn Daly Do for a Living?
That depends on which page you read. Several say she’s an actress who worked in summer stock theatre in the 1960s and 1970s. One obituary-style report calls her “actress Mary Glynn”. Others mention activism, mentorship and “social causes” without naming an organisation, a play or a year.
It’s possible she did stage work early in life. It’s also possible one page made a guess and the rest copied it, which is how this kind of profile spreads. No film or television credit turned up in my searches, and I found no theatre programme or review I could verify, so I’ve left the profession as unconfirmed.
Glynn Daly’s Age and Birthplace
Her age isn’t confirmed, and I found no reliable source for her birth date or birthplace. Several profiles skip the question altogether, which is probably the most honest approach available.
What I can say is that the youngest sibling, Tim, is 70, and the eldest I can date, Tyne, is 80. Glynn sits somewhere among the four. Since I can’t tell where from the sources, any age I gave you would be a guess, and that’s all you’ll see on pages that print one.
What Is Glynn Daly’s Net Worth?
There’s no figure worth trusting. She isn’t an officeholder or a company founder, so no filings or disclosures exist, and nobody has said how any estimate was reached.
It’s worth knowing how these numbers appear. A site needs something for its facts table, borrows a figure from a famous relative or a rival page, and the rest copy it. What her husband earned as a composer, or what her sister and brother have earned as actors, says nothing about her finances, and nothing public says how Snow’s estate was handled.
Where Is Glynn Daly Now?
Snow died at his home in Connecticut, and Wikipedia gives the town as Washington. One lifestyle page says Glynn “likely” lives in or near Connecticut on that basis. It’s a reasonable inference, but it’s a city-and-state guess about a private person who has recently lost her husband, and I haven’t confirmed anything more specific, so I’m leaving it there.
The same goes for the “quiet life as a grandmother” line that several pages repeat. It sounds right, and nobody can check it.
Rumours and Mistakes About Glynn Daly
The same errors keep circulating. She’s described as a working actress with a theatre career, as a mentor and activist, and as the “quiet architect” of the Daly acting family. None of those phrases comes with a source. Some pages give the marriage as 1967, others 1980, and a few leave it out.
It helps to look at how a claim is phrased. A real source says who, where and when. A weaker one says “reportedly” or “is known for her advocacy” and stops. One page I found has a heading about another woman’s father buried inside its own data, a sign that somebody pasted a template and didn’t check it. If a profile tells you she “chose privacy over stardom” and can’t name a single play, you can stop reading.
Why Glynn Daly Stays Out of the Spotlight
I won’t invent a reason. Plenty of people from famous families live quietly, and nothing suggests she has tried to profit from her connections. She has no verified social media account and no known interview, which you can observe even though the motive isn’t something she’s said.
Several pages call it a deliberate, even admirable choice. It may be. It may also be that she was never offered a public role, or never wanted one. Without her own words, a motive is just a story somebody else wrote.
Separating Facts From Myths About Glynn Daly
Reasonably well-supported: she’s the daughter of James Daly and Hope Newell, the sister of Tyne Daly and Tim Daly, and the wife of composer Mark Snow, who died on July 4, 2025. The couple had three daughters, and she was named as his surviving wife.
Weakly supported or unconfirmed: the year of the marriage, her work as a summer stock actress, her activism, her education, her exact age and where she lives now.
Not supported at all: that she’s a famous actress in her own right, that she’s a “quiet architect” of her family’s careers, that she’s connected to the person named in that leftover template heading, and any specific net worth.

Why People Keep Searching for Glynn Daly
It comes down to the family around her. Every Tyne Daly interview, every Tim Daly role and every retrospective on The X-Files sends a few people looking for the sister or the wife, and a relative with no public footprint is exactly the sort of search content farms love, because there’s demand and nothing on record to contradict whatever gets written.
That’s why the pages sound so alike. They’re answering a question the record can’t answer, and each one makes the next look more like consensus.
