Kathleen McNulty Rooney is an American real estate agent and philanthropist best known as the mother of Hollywood actresses Kate Mara and Rooney Mara.
She is also a granddaughter of Art Rooney Sr., the founder of the Pittsburgh Steelers, and her marriage to New York Giants executive Timothy Christopher Mara united two of the most storied families in NFL history.
Who is Kathleen McNulty Rooney?
Kathleen McNulty Rooney is a real estate agent from Westchester County, New York, and a member of the legendary Rooney family of Pittsburgh. She came to wider public attention through her daughters, Kate and Rooney Mara, both of whom became acclaimed actresses.
Her family background places her at the center of two powerful NFL dynasties. Her grandfather, Art Rooney Sr., founded the Pittsburgh Steelers in 1933. Her husband, Chris Mara, belongs to the Mara family, which founded the New York Giants in 1925.
Kathleen keeps a deliberately low profile. She rarely appears at public events and does not use social media. Her identity, however, is inseparable from two legacies: one built on football and one built on Hollywood.
She lives in Bedford, New York, in Westchester County, where she and Chris raised their four children. Her quiet approach to family life shaped two daughters who went on to earn Oscar nominations between them.
Early Life of Kathleen McNulty Rooney
Kathleen McNulty Rooney was born on August 28, 1964, in Allegheny County, Pennsylvania. Her father was Tim Rooney, the longtime operator of Yonkers Raceway and Empire City Casino, and her mother was June Rooney. She grew up as part of the extended Rooney clan in the Pittsburgh area.
The Rooney family name carries deep significance in American football. Kathleen’s grandfather, Art Rooney Sr., founded the Pittsburgh Steelers in 1933 with $2,500 in winnings from a horse race.
The team grew into one of the most successful franchises in NFL history, winning four Super Bowls between 1975 and 1980. Kathleen grew up in this legacy, attending family events and spending time at family-owned properties like the Palm Beach Kennel Club in Florida.
She has two sisters, Margaret Galterio and Bridget Rooney. The family maintained strong Irish Catholic traditions throughout Kathleen’s upbringing, with roots tracing back to Newry, County Down, in Ireland.

Kathleen McNulty Rooney Ethnicity and Nationality
Kathleen holds American nationality, born and raised in Pennsylvania. Her mother is of Irish and Italian descent, and her paternal Rooney ancestors originated in Newry, County Down, Ireland.
This Irish-Italian heritage has been a consistent thread in how both Kate and Rooney Mara have spoken about their family background in interviews.
Kathleen McNulty Rooney Height and Weight
Kathleen McNulty Rooney stands approximately 5 feet 4 inches tall, or around 1.63 meters. Her weight is not publicly confirmed. She is known for an understated, composed appearance at the rare public events she attends.
Kathleen McNulty Rooney Education
Kathleen met her future husband Timothy Christopher Mara at Boston College. The two first crossed paths in the mid-1970s at the Palm Beach Kennel Club in Florida, a dog-racing venue her family owned.
Chris had just started at Boston College at that time, while Kathleen was still in high school.
When Kathleen later enrolled at Boston College, the two began dating. Their time at the university brought them together and led to the marriage that would eventually link the Rooney and Mara families.
Kathleen McNulty Rooney Career
Kathleen McNulty Rooney’s professional life has centered on real estate in Westchester County, New York. Wikipedia’s article on Rooney Mara describes her mother as a part-time real estate agent, a description that has appeared consistently across multiple sources.
She has worked as a licensed real estate broker in the Westchester area for a number of years. The role suited the family’s base in Bedford, New York, a town in Westchester County roughly 40 miles north of New York City.
Real Estate Work in Westchester
Kathleen’s work as a real estate agent allowed her to maintain a professional identity separate from her family name. Westchester County is one of the most active real estate markets in the New York metropolitan area, and brokers there handle some of the region’s most valuable residential transactions.
She took this path while also managing a household that included four children and a husband deeply embedded in the NFL front-office world. The combination made for a low-profile but active professional life.
Her income from real estate work formed the personal side of her earnings, separate from the Rooney family’s broader wealth.
Family Legacy and NFL Connections
Beyond her own career, Kathleen’s position at the intersection of the Rooney and Mara families gives her a unique place in NFL history.
Her grandfather, Art Rooney Sr., used $2,500 in horse-race winnings to found the Pittsburgh Steelers in 1933. The Steelers went on to become one of the most decorated franchises in NFL history.
On her husband’s side, the Mara family founded the New York Giants in 1925. Tim Mara, Chris’s grandfather, built the franchise from scratch, and Wellington Mara later co-owned the team for decades.
Chris Mara currently serves as Senior Vice President of Player Personnel for the Giants, overseeing scouting and player evaluation.
Kathleen also developed a deep appreciation for art, antiques, and classic films, interests she reportedly shared with her daughters. Rooney Mara has spoken publicly about her mother’s eye for vintage style and how it shaped Rooney’s own aesthetic sensibility.
Supporting Her Daughters’ Careers
Both Kate and Rooney Mara have spoken of growing up in a household that valued creativity alongside sport. Kate Mara debuted in Random Hearts in 1999 and later became known globally for her role as reporter Zoe Barnes in House of Cards on Netflix.
Rooney Mara earned an Academy Award nomination for Best Actress for her role in Carol (2015) and a nomination for Best Supporting Actress for The Girl with the Dragon Tattoo (2011).
Kathleen’s support for her daughters has been consistent but quiet. She rarely appears at premieres, preferring to stay out of their professional spotlight while remaining present in their personal lives.
Kate and Rooney both carry the name Rooney in tribute to their mother’s family: Kate’s middle name is Rooney, while Patricia took it as her professional first name.
Kathleen McNulty Rooney Husband
Kathleen McNulty Rooney married Timothy Christopher Mara, known to the family as Chris, in January 1981. Chris Mara is the Senior Vice President of Player Personnel for the New York Giants, a position that places him at the heart of the team’s scouting and roster decisions.
The Giants are one of the NFL’s founding franchises, established by his grandfather Tim Mara in 1925.
The couple met at the Palm Beach Kennel Club in the mid-1970s, when Kathleen’s family owned the dog-racing venue in Florida. Chris had just started at Boston College, and Kathleen was in high school. They met again when she enrolled at the same university, and they began dating from that point.
Their marriage in 1981 united the Rooney and Mara families formally. Sports historians have noted this as a rare union of two NFL founding dynasties. Between the Steelers and the Giants, the two families hold a combined ten Super Bowl rings.
Chris and Kathleen have remained married for over four decades. They raised their four children in Bedford, New York, and continue to be based in Westchester County.
Chris has continued his role with the Giants into 2026, with reports noting that one of his recent moves was supporting the hiring of head coach John Harbaugh in January 2026.
Kathleen McNulty Rooney Children
Kathleen and Chris Mara have four children: Daniel Mara, Kate Mara, Patricia Rooney Mara (known professionally as Rooney Mara), and Conor Mara. Kate and Rooney have both built major careers in Hollywood, while Daniel and Conor have remained largely out of public life.
Kate Mara was born on February 27, 1983, in Bedford, New York. She is best known for her role as Zoe Barnes in House of Cards and for her appearance in The Martian (2015). She married actor Jamie Bell in 2017, and the couple has two children together.
Rooney Mara was born on April 17, 1985, also in Bedford, New York. She earned back-to-back Oscar nominations and is currently partnered with actor Joaquin Phoenix, with whom she has a son named River.
