Gary Sinise’s Kids: Meet Daughters Sophie, Ella & Late Son Mac Sinise – Hollywood Life

Gary Sinise chose November 10, 2026, to release Graceful Warrior because it would have been his son Mac’s 36th birthday. The book follows Mac, a drummer and composer, through the years he lived with chordoma, a rare cancer, and recounts how the Sinise family cared for him before his death in January 2024. “It was a heck of a journey, a difficult one, but one that we traveled together,” Gary said, per People.

Gary and his wife, Moira Harris, raised three children. Their daughters, Sophie and Ella, joined their parents for the interview and shared their own memories of Mac. Learn more about all three siblings, including the music Mac left behind and how it continues to support the foundation where he worked.

Sophie Sinise

Sophie, Gary and Moira’s eldest child, is a hairstylist. She also acted in Swamp Shark and appeared on CSI: NY, the series her father starred in. Sophie and her husband, Bobby, moved their family from California to the Nashville area, where she and her sister, Ella, now live near their parents. Sophie has three children.

In November 2026, Sophie told People that her brother Mac could lift her spirits even as his cancer progressed. “He made you feel better when you walked in the room,” she said. She also described a more recent family gathering at her parents’ house, where all six grandchildren spent the day swimming and eating ice cream while Mac’s music played.

Ella Sinise

Ella, Gary and Moira’s youngest child, began her teaching career in Washington, D.C. She took leave from her job at one point to spend time with Mac as his illness progressed. Ella remembered that even as he lost mobility, he learned to play the harmonica, watched Cubs games with their mom and prayed with her. Ella has three children and lives near her parents and sister in Tennessee.

Ella and Sophie appeared together on the Gary Sinise Foundation’s podcast in 2024. They talked about growing up in Hollywood, their family’s work with veterans and what the foundation meant to them. In a separate People interview, Ella said she understood why her father stepped away from acting to be with the family. “And, sure, he did some acting, but that’s not his identity,” she said.

McCanna “Mac” Sinise

McCanna Anthony “Mac” Sinise was a drummer and composer who studied popular music at the University of Southern California. While there, he co-wrote “Gunslingers of Zanthia” with Shane Fogerty, the son of Creedence Clearwater Revival’s John Fogerty. Mac also created the Gary Sinise Foundation’s podcast, which features conversations with veterans and first responders.

Mac died on January 5, 2024, at age 33 after living for more than five years with chordoma, a rare cancer. He worked on music that became Resurrection & Revival, and proceeds from the album series benefit the Gary Sinise Foundation. Gary released Graceful Warrior, a book about Mac and how the family cared for one another during his illness, on November 10, 2026, which would have been Mac’s 36th birthday.
