The McElhenney Family Unfiltered: Why Rob's Sons And Wife Kaitlin Olson Are 'Unhappy' With His Latest Move
The McElhenney family, led by *It's Always Sunny in Philadelphia* creator Rob McElhenney and his wife, co-star Kaitlin Olson, remains one of Hollywood's most unconventional and beloved power couples. As of late December 2025, the family is navigating a new wave of public attention, not just from the continued success of their hit shows and their ownership of Wrexham AFC, but from a surprising and controversial personal decision: Rob’s plan to legally change his name, a move that has reportedly left his immediate family "unhappy."
The couple, known for their hilarious on-screen dynamic as Mac and Dee Reynolds, maintain a fiercely private life for their two sons, Axel and Leo, yet recent interviews have offered a rare glimpse into their home, revealing the challenges of balancing a massive creative empire—from Paddy's Pub to the Welsh football pitch—with the realities of raising two teenagers. This deep dive into the McElhenney household explores the latest updates on their family unit, their shared business ventures, and the drama surrounding the potential end of the "McElhenney" name.

The Dynamic Duo: Rob McElhenney and Kaitlin Olson's Unconventional Romance
The love story between Rob McElhenney and Kaitlin Olson began in 2005 on the set of *It's Always Sunny in Philadelphia*. McElhenney, the show’s creator, was immediately captivated by Olson, who plays the abrasive and often-mocked Dee Reynolds. The relationship began in secret, with the couple keeping their dating life hidden from the rest of "The Gang" cast for a year and a half.
They married in 2008, a union that blended their professional and personal lives into one of the most stable, albeit unconventional, marriages in Hollywood. Their relationship is often noted for its deep foundation in humor and mutual respect, despite their characters' toxic on-screen dynamic.
In mid-2025, Olson, who is also busy with her own projects like the series *High Potential*, spoke openly about the balance required to manage their careers, their business ventures like Wrexham AFC, and their family. She confirmed that even after over 17 years together, they still face the everyday struggles of modern parenthood, a refreshing admission from a celebrity couple.
Raising The Next Generation of 'The Gang': Sons Axel and Leo
Rob and Kaitlin are parents to two sons: Axel Lee, born in 2010, and Leo Grey, born in 2012. As of late 2025, Axel is 15 years old and Leo is 13 years old.
The couple has been notoriously private about their children, a conscious decision to give them a normal upbringing away from the spotlight. However, as the boys enter their teenage years, the parents have begun to loosen the reins slightly. In a recent update, Rob and Kaitlin admitted they have started letting their sons watch the cult-favorite show that brought their parents together, *It's Always Sunny in Philadelphia*.
This decision is a significant milestone for the family, as the show's famously dark and inappropriate humor is a far cry from typical family viewing. The boys' reaction to seeing their parents play such outlandish characters—Mac and Dee—has become a fun, new dynamic in the household.
The McElhenney-Olson family also maintains a strong focus on philanthropy. In 2025, they were recognized as "Guardians" by the Alliance for Children's Rights, underscoring their commitment to causes beyond their Hollywood careers.
The Name Change Drama: Why 'Rob Mac' Has His Family 'Unhappy'
The most surprising and current family news centers on Rob McElhenney’s recent announcement that he plans to legally change his last name to "Mac," effectively becoming "Rob Mac."
This is not a joke from a sitcom plot. The actor reportedly filed the paperwork in mid-2025, explaining that the name change was inspired by the widespread use of the nickname "Rob Mac" by fans, colleagues, and even family members. He suggested the move was a nod to his public persona and a simplification of his lengthy full name, Robert McElhenney III.
However, the reaction from his inner circle was less than enthusiastic. Multiple reports indicated that Kaitlin Olson and their two sons, Axel and Leo, were "unhappy" and "extremely unhappy" about the decision.
Kaitlin Olson, whose legal name is Olson McElhenney, publicly commented on the switch, stating, "I'm legally Olson McElhenney, but I go by Olson, so I don't really have to deal with it, but I don't love it." The boys' displeasure reportedly stems from the potential for confusion and the loss of their established family name. This highly public, yet deeply personal, family conflict over identity and legacy shows that even Hollywood royalty faces relatable domestic disagreements.
From Paddy's Pub to Wrexham AFC: The Family Business Empire
The McElhenney family unit extends far beyond their home life and the set of *It's Always Sunny in Philadelphia*. Their shared and individual business ventures are a testament to their entrepreneurial spirit.
McElhenney’s most high-profile venture is the co-ownership of the Welsh football club, Wrexham AFC, with actor Ryan Reynolds. The documentary series *Welcome to Wrexham* has brought international attention to the club and, by extension, to Rob's business acumen.
In a recent development in late 2025, Reynolds and McElhenney sold a minority stake in Wrexham AFC to the Allyn family, known for their business interests. This move was framed as a strategic investment to provide more capital for the club's continued growth in EFL League One, further cementing Wrexham’s future success.
Furthermore, McElhenney's creative and business portfolio includes RCG Productions, the company responsible for *It's Always Sunny* and *Mythic Quest*, and his newer multimedia company, More Better Industries, which oversees film, marketing, and other ventures. These entities ensure that the McElhenney-Olson family remains a dominant force in both entertainment and sports, with Kaitlin Olson herself starring in RCG-produced projects. Their combined efforts demonstrate a powerful, shared vision that drives their collective empire forward.
