Bridget Rooney is a name many people search after hearing about Kevin Costner, Bill Koch or the Pittsburgh Steelers. This Bridget Rooney biography tells you who she is, where she comes from and what the public record says about her family and life. We also tell you plainly where facts are missing, so you never get guesses dressed up as truth.
Who Is Bridget Rooney and Why Does She Matter?
Bridget Rooney, also written as Bridget Rooney Koch, is an American woman from the famous Rooney family of Pittsburgh. Her grandfather, Art Rooney Sr., founded the Pittsburgh Steelers football team. She is also the mother of Liam Costner, whose father is actor Kevin Costner, and the wife of billionaire businessman Bill Koch.
Why do people care? Think of a family tree as a big oak. Art Rooney Sr. is the thick trunk, and Bridget is one branch that grew toward sports, Hollywood and business at the same time. Most of what people know about her comes through those three famous links, not through a public career of her own.

Current Status as of October 21, 2026
As of October 21, 2026, the reports I could find still describe Bridget Rooney as married to Bill Koch. They say she lives a mostly private life, with Palm Beach, Florida, named as the family’s home. I found no recent news of a divorce, a new career move or any public statement from her.
Early Life and Family Background
Bridget was born into what one report calls a prominent Irish Catholic family. The Rooneys are known across America for the Steelers, one of the oldest teams in the National Football League. Her late uncle, Dan Rooney, was a longtime Steelers owner and leader.
Reports say she grew up in a home with several brothers and sisters. Her sister Kathleen is linked in some reports to the actresses Kate and Rooney Mara, which would make Bridget their aunt. Growing up around such a famous name probably shaped her, yet she has never told her childhood story in a book or a long interview.
Age and Birthday
Here is where the facts get messy. Two reports give her birth date as April 26, 1962. Another says May 1962. A third says February 26, 1970. Since most sources point to 1962, she would be about 64 years old as of October 21, 2026.
Parents and Siblings
Her father is Tim Rooney, a son of Art Rooney Sr. Her mother is June Rooney, reported to have been born June Marraccini. Reports name her siblings as Kathleen, Margaret, Cara, Timothy James Jr. and Thomas Joseph. Treat the full sibling list as reported, not official, because I could not match it to a family statement.
Education
No reliable source names her school, college or degree. If you see a website listing a university for her, ask where that site got the claim. It is better to say “not publicly confirmed” than to guess.
State of Origin
She is American, and reports say she was born in Pittsburgh, Pennsylvania, the home city of the Rooney family and the Steelers. If you were hoping for a “state of origin” in the Nigerian sense, note that this term does not apply here. Her state of origin is simply Pennsylvania, according to those reports.
Religion
Bridget has never spoken publicly about her personal faith. Her family is described as Irish Catholic, so many writers assume she is Catholic too. That is a guess about her family, not a confirmed fact about her own beliefs.
Career
Bridget Rooney does not have a long public career like an actor or a singer. One report says she worked at a television station in Aspen, Colorado, around the time she met Kevin Costner. Some sites call her an actress, but I found no film or show credits to back that up.
In later years she is linked to Oxbridge Academy, a private school in West Palm Beach, Florida. Some reports say she and Bill Koch founded it together, while others credit Bill Koch alone. Either way, she is described as a supporter of the school. Is that a “career”? It is more like a family project, and that is how I describe it.
Husband and Children
In 1996, Bridget had a brief romance with Kevin Costner, soon after his divorce from Cindy Silva. Their son, Liam Timothy Costner, was born in November 1996, according to most reports. Several reports say a paternity test was done and that Costner accepted Liam as his son. The two were never married.
She later married Bill Koch in 2005, according to several sources. Bill is a businessman, sailor and collector from the Koch family, and reports say his brother David was his best man. Together they have a daughter, Kaitlin, reported to be born around 2006. Bill also has other children from earlier relationships, so the family is a blended one.
Height
One biography site says she stands 5 feet 8 inches, or 173 centimetres. I could not confirm it with a second reliable source, so please treat it as a reported figure.
Net Worth
There is no verified net worth for Bridget Rooney. Websites toss around numbers from $10 million to $50 million, but none show proof. What we do know is that her husband is a billionaire and her family is linked to a major sports team. How much of that wealth is hers alone is not public.
Social Media
One website says she has Twitter and Instagram accounts, but I could not verify any official account in her name. Many fan pages and fake profiles use famous names, so I am not adding links here. If you want to follow family news, look at the official pages of the Pittsburgh Steelers or Oxbridge Academy instead of unknown accounts.
