Inside the Family Lives of the NCIS Cast

Marc Harmon’s 2 Sons

Harmon starred as beloved special agent Gibbs for 19 seasons before leaving NCIS in 2021. The Ghosts of Honolulu author and his wife of nearly four decades, Pam Dawber, are proud parents to two sons: Sean and Ty Christian.

Harmon and Dawber became parents when they welcomed Sean in April 1988. They had a second son, Ty, in June 1992. Ty is a screenwriter and visual effects artist who has worked on various films and television shows, including Thor: Love and Thunder, Venom and The Electric State.

Meanwhile, Sean also got involved in the entertainment industry and works as an actor and stuntman. One of Sean’s most notable roles is a young version of his dad’s NCIS character, which he has performed in seven episodes over the years.

Although Harmon has mostly kept his personal life out of the spotlight, he has expressed how proud he is of both his sons.

“Separate from anything as an actor, you hopefully take pride in who people are individually away from any camera just as people, as citizens,” Harmon told ET in 2020. “And both our boys have done well and hopefully made smart choices and are doing well daily … we have a lot of reasons to be proud of both of them.”

Sean Murray’s 2 Children

Murray has acted as NCIS Senior Field Agent Timothy McGee since the show premiered in 2003. Just like in the series, Murray is also a dad to two children.

The Hocus Pocus actor welcomed daughter Caitlyn in 2007 and son River in 2010 with his ex-wife, Carrie James.

In 2022, Murray revealed that Caitlyn would be guest-starring in an episode of NCIS.

“I am pleased to introduce my daughter, Cay Ryan Murray, into the on-screen world of NCIS! Cay guest stars in our upcoming May 2 episode, and I couldn’t be more proud,” Murray captioned a photo of them on set.

Brian Dietzen’s 2 Children

Dietzen, who plays Dr. Jimmy Palmer, shares two children — daughter Clover and son Satchel — with his wife, Kelly Dietzen.

The actor does not share photos of his children on social media, but he shared that Clover likes music and Satchel enjoys video games when getting his golf clubs engraved with their names and favorite things in 2022.

Dietzen also frequently posts with his wife of two decades and expresses his gratitude for her as a mother.

“Happy Mother’s Day to you all. Today, our family is celebrating this woman right here,” he captioned a photo of them in May 2022. “You’re the best, Kel. Our kids lucked out by getting you as their mom.”

Wilmer Valderrama’s 2 Children

Although Valderrama plays the rough-around-the-edges Special Agent Nicholas Torres, in reality, he’s a dad to two young children.

The That ‘70s Show actor became a father in February 2021 when his fiancée, Amanda Pacheco, welcomed their first child, daughter Nakano Oceana. They had their second child, son Wolf Monte, in July 2025.

Valderrama told PEOPLE in September 2025 that being a working dad of two can be “pretty challenging,” but he credited Pacheco for “making it look easy.” He also said that Nakano is an “awesome” big sister.

“She’s having a great time. She’s really about it. She loves her baby brother,” he said. “She goes to the grocery store, she’s putting stuff in the cart for him and so far so good. We’ll see what happens when he starts grabbing her toys.”

Rocky Carroll’s Daughter

Carroll, who has portrayed NCIS Director Leon Vance since season 5, has one child, daughter Elissa, with his wife, Gabrielle Bullock.

Although Carroll and Gabrielle, who tied the knot in 1996, keep much of their personal lives private, Gabrielle occasionally shares sweet moments of the three of them spending time together on Instagram.

In April 2023, she posted a photo of Elissa and Carroll walking together and captioned the picture, “Father & Daughter 💕.”

Gary Cole’s Daughter

After Harmon left NCIS in 2021, Cole joined the cast as NCIS Supervisory Special Agent Alden Parker. Off-screen, Cole has one child, daughter Mary, with his late ex-wife, Teddi Siddall.

The Midnight Caller actor, who has since married Michelle Knapp, spoke to WebMD magazine in 2009 about Mary’s autism diagnosis, which she received when she was a toddler in 1995.

“[She] didn’t process information like you or I do, and did not pick up on social cues,” he explained, while advising others, “Seek answers, and the earlier the better.”

In addition to his daughter, Cole is also a stepfather to Knapp’s children. The couple tied the knot in 2021.
