Kathleen McNulty Rooney isn’t a Hollywood actress or a TV personality. She’s the woman who connects two of the NFL’s most powerful ownership families — and she’s the reason Kate Mara and Rooney Mara can claim both the Pittsburgh Steelers and the New York Giants as part of their bloodline.
Born on August 28, 1964, in Allegheny County, Pennsylvania, Kathleen grew up a Rooney — the family that’s owned the Steelers since Art Rooney Sr. founded the franchise in 1933. She then married into the Mara family, which has controlled the New York Giants since Tim Mara started that team in 1925. That single marriage merged two NFL dynasties that had operated separately for decades.
Early Life and the Rooney Family
Kathleen was raised in Western Pennsylvania’s Allegheny County, deep in Steelers country. Her father, Timothy James Rooney, served as president of Yonkers Raceway and held a direct connection to the Steelers ownership lineage through the founding Rooney family. Art Rooney Sr. — Kathleen’s grandfather — bought the Pittsburgh Pirates (later renamed the Steelers) for $2,500 in 1933 and built the franchise into one of the NFL’s most storied organizations.
Growing up in this environment meant football wasn’t a hobby — it was the family business. The Rooneys were fixtures in Pittsburgh’s civic and sporting life. Kathleen grew up alongside sisters Margaret Galterio and Bridget Rooney, surrounded by a family whose name carried weight across professional sports and horse racing.
The Rooney-Mara NFL Connection
Kathleen married Timothy Christopher Mara, a vice president of player evaluation for the New York Giants. Timothy comes from the Mara family that founded the Giants — his ancestor Tim Mara paid $500 for an NFL franchise in 1925, and the family has maintained ownership ever since.
This wasn’t an arranged merger of football royalties, but the result was historic: two families that had each owned NFL teams for nearly a century were now linked through marriage. The Rooney-Mara union meant their children grew up with direct ties to both the Steelers and the Giants — rival NFC/AFC franchises that have combined for 10 Super Bowl titles.
Together, Kathleen and Timothy raised four children: Daniel, Kate, Patricia (known professionally as Rooney Mara), and Conor. The family settled in Bedford, New York, a wealthy Westchester County suburb about 50 miles north of Manhattan.
Her Famous Daughters
While the Rooney and Mara families are NFL royalty, Kathleen’s daughters went a different direction — straight into Hollywood.
Kate Mara (born February 27, 1983) started acting at age nine in a school musical and landed her first TV role on Law & Order in 1997. She broke through nationally as reporter Zoe Barnes in Netflix’s House of Cards (2013-2014) and went on to star in The Martian, Megan Leavey, and A Teacher. Kate married British actor Jamie Bell in 2017, and they have two daughters together.
Patricia Rooney Mara (born April 17, 1985) took her mother’s maiden name as her professional first name — a direct nod to the Rooney legacy. Her breakout came with David Fincher’s The Girl with the Dragon Tattoo (2011), earning her a Best Actress Oscar nomination. She picked up a second Academy Award nomination for Carol (2015) and won the Best Actress prize at the Cannes Film Festival that same year. Rooney’s in a long-term relationship with Joaquin Phoenix, and they have a son named River, after Phoenix’s late brother.
Both daughters inherited their mother’s connection to the Rooney family — Patricia literally wears it as her stage name.
Career
Away from the NFL spotlight and her daughters’ film careers, Kathleen McNulty Rooney works as a real estate broker. She’s kept the specifics of her professional life largely private, which fits a pattern — Kathleen has consistently avoided the press and doesn’t maintain any public social media accounts.
That low profile is deliberate. With a husband who’s a Giants executive, two daughters who walk red carpets, and a last name that’s synonymous with Pittsburgh football, staying out of the public eye takes effort. Kathleen’s managed it for decades.
