Bridget Rooney belongs to the well-known Rooney family, whose name has long been connected with the Pittsburgh Steelers and American sports. However, many people know her for a different reason: she shares a son with actor Kevin Costner and later married businessman William “Bill” Koch. Despite these famous connections, Bridget has kept much of her own life away from public attention.

Who Is Bridget Rooney?
Bridget Rooney is an American woman from one of the country’s best-known sporting families. Her grandfather, Art Rooney, founded the Pittsburgh Steelers, giving the Rooney name a lasting place in National Football League history.
Her family has also been involved in horse racing, business, public service, and entertainment. The Steelers have remained strongly connected to the Rooney family since the team began in 1933.
Bridget did not build the same type of public career as some of her famous relatives. Instead, most public interest in her comes from her family background, her former relationship with Kevin Costner, and her marriage to Bill Koch.
She has attended several social, cultural, and charity events, but she rarely gives public interviews. Editorial photographs show her at events with her husband, yet she does not appear to seek regular media attention.
How Is Bridget Rooney Connected to the Pittsburgh Steelers?
Bridget Rooney is a granddaughter of Art Rooney, the businessman who founded the Pittsburgh Steelers.
Art Rooney created the franchise in 1933. His family continued to own and manage the team after his death, making the Rooneys one of the longest-serving ownership families in American professional sports.
This family connection is an important part of Bridget’s story. She grew up with a surname associated with football, business, tradition, and public responsibility.
However, there is no strong public evidence that Bridget has held a major management position with the Steelers. Her connection is mainly through her family rather than through a confirmed executive role.
Who Are Bridget Rooney’s Parents?
Several online profiles identify Bridget’s father as Timothy James Rooney. He has been associated with the family’s horse-racing interests and became known for his leadership at Yonkers Raceway.
The Harness Racing Museum describes Timothy J. Rooney as an influential figure in Standardbred racing and a longtime racetrack leader.
Some biography websites identify Bridget’s mother as June Marraccini. However, detailed information about Bridget’s parents, siblings, childhood, and education has not been widely documented by strong primary sources.
For that reason, claims about her early life should be treated carefully.
Is Bridget Rooney Related to Kate Mara and Rooney Mara?
Yes, Bridget Rooney belongs to the wider family that also includes actresses Kate Mara and Rooney Mara.
The family link joins two famous American sports families. Through their mother, Kate and Rooney Mara are connected to the Rooney family, while their father comes from the Mara family associated with the New York Giants.
Bridget and the Mara sisters are relatives, although many websites describe the exact connection differently. She is commonly described as their cousin.
Their public lives are very different. Kate and Rooney Mara developed major acting careers, while Bridget has generally remained a private social figure.
What Happened Between Bridget Rooney and Kevin Costner?
Bridget Rooney had a relationship with Kevin Costner during the 1990s.
The relationship took place after Costner’s first marriage ended. It did not lead to marriage, but Bridget and Costner welcomed a son, Liam, in November 1996.
Many entertainment websites have published dramatic stories about their relationship. Some repeat claims about disagreements, paternity testing, and financial arrangements.
However, much of that information comes from secondary celebrity websites rather than direct statements from Bridget, Liam, or Costner. Readers should therefore avoid treating every detail as confirmed fact.
The most reliable point is simple: Bridget Rooney and Kevin Costner share a son, but they did not remain a couple.
Who Is Bridget Rooney’s Son, Liam Costner?
Liam Costner was born in November 1996. He is the son of Bridget Rooney and Kevin Costner.
Unlike several members of his father’s family, Liam has remained largely outside the entertainment industry. Recent profiles note that both Liam and his mother have generally avoided the spotlight.
Some websites describe him as working in real estate. Nevertheless, detailed information about his job, relationships, finances, and daily life remains limited.
This privacy is important. Liam has famous parents, but he has not built a highly public celebrity career of his own.
Did Bridget Rooney Marry Kevin Costner?
No, Bridget Rooney and Kevin Costner never married.
Their relationship was relatively brief, and they went in separate directions after Liam’s birth. Costner later married model and designer Christine Baumgartner in 2004, although that marriage later ended.
Bridget eventually married businessman Bill Koch in 2005.
Because Bridget is often introduced as “Kevin Costner’s former partner,” some readers wrongly assume they were once husband and wife. Public records and reliable profiles do not support that claim.
Who Is Bridget Rooney’s Husband, Bill Koch?
Bridget Rooney’s husband is William Ingraham “Bill” Koch, an American businessman, art collector, sailor, and philanthropist.
He founded the business that became Oxbow Carbon after leaving his family’s company in the early 1980s. Oxbow currently describes him as its founder and executive chairman.
Bill Koch is also known for leading the America³ sailing team that successfully defended the America’s Cup in 1992. The official America’s Cup history credits his team’s technology, research, and sailing program as major parts of that victory.
He comes from the famous Koch business family. However, he followed a business path separate from his brothers Charles and David Koch.
When Did Bridget Rooney and Bill Koch Get Married?
Bridget Rooney and Bill Koch married in 2005.
Public reports state that the wedding took place in Colorado. Forbes also described Bridget as a member of the Pittsburgh Steelers family when discussing Bill Koch’s wedding.
Their relationship has lasted for more than two decades. A 2025 report in The Wall Street Journal still referred to Bridget as Bill Koch’s wife while discussing the couple’s decision to sell an Aspen property.
The couple has appeared together at art, charity, education, and cultural events. Still, they usually keep the personal side of their marriage private.
Does Bridget Rooney Have a Daughter?
Bridget Rooney and Bill Koch have one daughter together, commonly identified as Kaitlin Koch.
Kaitlin is sometimes called “K.K.” in entertainment profiles. She has not developed a highly public career, and verified information about her personal life remains limited.
Bridget is also connected to Bill Koch’s children from earlier relationships. However, private family relationships should not be described beyond what the family has made public.
Her two publicly known biological children are Liam Costner and Kaitlin Koch.
How Many Children Does Bridget Rooney Have?
Bridget Rooney has two publicly known children.
Her son Liam was born during her relationship with Kevin Costner. Her daughter Kaitlin was born during her marriage to Bill Koch.
| Child | Father | Public profile |
|---|---|---|
| Liam Costner | Kevin Costner | Mostly private |
| Kaitlin Koch | Bill Koch | Mostly private |
Both children come from families with major names in entertainment, business, and sports. Even so, neither appears to seek the level of public attention attached to their parents.
Is Bridget Rooney an Actress?
Many online biography pages call Bridget Rooney an actress and connect her with a small project titled Zombie or Not Zombie.
However, there is little strong evidence of a significant or continuing professional acting career. Major coverage of Bridget usually identifies her through the Rooney family, her relationship with Kevin Costner, or her marriage to Bill Koch.
It is safer to describe her as a private social figure rather than a well-established actress.
This distinction matters because celebrity biography websites often repeat the same unverified description without checking the original source.
What Does Bridget Rooney Do for a Living?
Bridget Rooney’s current occupation has not been clearly confirmed in reliable public sources.
She has appeared at social and cultural events and is associated with families known for business, sports, education, and philanthropy. Yet that does not prove she holds a particular professional title.
Some websites describe her as an actress, socialite, philanthropist, or businesswoman. These descriptions may partly reflect her family and social connections rather than a documented full-time career.
Without a direct professional profile or verified statement, it would be wrong to assign her a specific job.
Is Bridget Rooney Involved With Oxbridge Academy?
Bill Koch founded Oxbridge Academy in West Palm Beach, Florida, in 2011. The independent school serves students in grades six through twelve and focuses on college preparation.
Some online articles connect Bridget with the school because she is married to its founder and has appeared in Palm Beach social circles.
However, Oxbridge Academy’s official information names Bill Koch as the founder and visionary. It does not clearly present Bridget as the school’s founder or current leader.
Therefore, articles should not claim that Bridget founded or operates the school unless stronger evidence becomes available.
What Is Bridget Rooney’s Net Worth?
Bridget Rooney’s personal net worth is not publicly confirmed.
Many websites publish large estimates, often based on the wealth of her husband or the value connected with her extended family. That method does not show how much money Bridget personally owns.
Bill Koch is a wealthy businessman, but his fortune should not automatically be presented as Bridget’s individual net worth.
Personal assets, trusts, property ownership, business interests, and marriage agreements are private. Without dependable financial records, any exact Bridget Rooney net worth figure would be speculation.
How Old Is Bridget Rooney?
Several online profiles report that Bridget Rooney was born in 1962. Some give May 26 as her birthday.
Bill Koch’s public biography information also lists Bridget’s birth year as 1962, but stronger primary confirmation of her full birth date remains difficult to find.
Based only on the widely reported year, she would be around 64 in 2026. Still, websites should clearly explain that the exact date has not been firmly verified.
Using cautious wording is better than turning a repeated online claim into a false certainty.
Where Does Bridget Rooney Live?
Bridget Rooney and Bill Koch have long been connected with Palm Beach, Florida.
The couple has also owned or used properties in places such as Colorado and Cape Cod. A 2025 property report described them as empty nesters while discussing the sale of their Aspen-area compound.
However, a person’s exact current home address is private information and should not be published.
It is enough to say that Bridget has strong public ties to Palm Beach and has spent time at family properties in other parts of the United States.
Why Does Bridget Rooney Keep Her Life Private?
Bridget has famous connections on nearly every side of her family.
Her grandfather founded the Pittsburgh Steelers. Her former partner is an award-winning Hollywood actor. Her husband is a billionaire businessman, sailor, and art collector.
Despite this unusual position, Bridget rarely speaks publicly about her relationships, children, or personal history.
Her privacy may explain why so many questionable stories appear online. When a person does not give interviews, low-quality websites often fill the information gap with guesses.
Responsible articles should separate verified facts from repeated rumours.
Why Are People Still Searching for Bridget Rooney?
Interest in Bridget Rooney comes from several different audiences.
Football fans search for her Rooney family connection. Movie fans want to understand her past with Kevin Costner. Business readers recognize the Koch surname, while celebrity readers want information about Liam Costner.
Her story also connects four influential American worlds:
- Professional football
- Hollywood entertainment
- Large private businesses
- Wealthy philanthropic circles
That combination makes her interesting even though she has not built a public career based on fame.
Common Misunderstandings About Bridget Rooney
One common mistake is calling Bridget Kevin Costner’s former wife. They had a relationship and share a son, but they never married.
Another mistake involves her career. Many pages present her as a famous actress, although there is little proof of a major acting history.
People also confuse her wealth with Bill Koch’s fortune. Her husband is wealthy, but Bridget’s individual net worth has not been confirmed.
Finally, some sources describe her as an owner or manager of the Pittsburgh Steelers. She is a member of the Rooney family, but no reliable evidence shows that she currently controls the team or holds a leading team position.
Final Thoughts
Bridget Rooney is best known for the remarkable families and public figures around her. She is a granddaughter of Steelers founder Art Rooney, the mother of Kevin Costner’s son Liam, and the wife of businessman Bill Koch.
Yet Bridget’s own life remains largely private.
Reliable information confirms her major family connections, her 2005 marriage, and her two children. Details about her exact birthday, career, education, personal fortune, and daily activities remain less certain.
Her story is interesting, but it should be told without inventing facts or turning private family matters into gossip.
