Meet Gary Sinise’s 3 kids and 5 grandkids — plus the tragic death that convinced him to leave Hollywood

Gary welcomed his first child, a daughter named Sophie, in November 1988 with his longtime wife Moira Harris. The couple tied the knot in 1981.

Sophie grew up in Southern California while her dad made waves in Hollywood, and occasionally ventured into acting as well. Her credits include the TV movies Swamp Shark and The Heart of Christmas (both 2011), plus an appearance on her dad’s TV show CSI: NY in 2010.

However, soon after, she began taking a more active role with The Gary Sinise Foundation, a nonprofit organization her father founded in 2011 devoted to the service and care of veterans, first responders and their families.

“I was one of the first receptionists at the Gary Sinise Foundation,” she said during an appearance on the foundation’s podcast. “I remember I needed a job so he put me to work at his little office, right across from the studio at CSI.”

Not much is known about her personal life. She is married to a man named Bobby and they live in Nashville, Tennessee, close to her parents. They have at least one child together.

Ella is the youngest of Gary and Moira’s three kids, born in 1992. Not much is known about her. She only has one screen credit, appearing in the 2011 documentary Lt. Dan Band: For the Common.

She has also involved herself with work on her father’s foundation with her big sister, making an appearance on the same podcast as well to discuss their relatively normal upbringing.

“We just had a normal upbringing where mom took us to soccer practice and did all the normal things, and she didn’t want to go to all the Hollywood stuff,” she explained. 

There is no information on whether Ella is married, but she also has kids of her own, at least one daughter. Between Ella and Sophie, Gary has five grandchildren ages one to eight, to whom he is “Papa.”

Mac was born to Gary and Moira in 1990. Mac was primarily a musician, studying songwriting and composition at the University of Southern California’s Thornton School of Music, and playing drums for the Lt. Dan Band.

In 2017, he joined the foundation as assistant manager of education and outreach. In 2018, however, not long after his mom was diagnosed with breast cancer, Mac was diagnosed with Chordoma, a rare type of bone cancer.

“It looked like a monster grabbing my son’s spine,” Gary told People of seeing the MRI scan of his son’s diagnosis. He stepped away from acting in 2019 to care for his son. Moira entered remission after a few months of treatment and is currently cancer free.

Mac tragically passed away in January 2024 at the age of 33. The Forrest Gump star shared that he plans to release his son’s music that he’d been working on before and during his condition through an album titled Mac Sinise: Resurrection and Revival.
