The pair married in 1981, and in his, “Grateful American,” the actor shared that their wedding, though planned for years, happened without much fanfare — they didn’t even have rings at the time.

The couple went on to welcome three children — Sophie, Mac, and Ella. Beyond motherhood, Moira enjoyed a notable career in the entertainment industry, starring in films such as “One More Saturday Night,” “Of Mice & Men,” and “Terminator 3: Rise of the Machines.”

She also appeared in Disney’s “Tall Tale” in 1995 and delivered an Emmy-winning performance in “Murder in Green Meadows” in 1987.

At one point, Moira was a member of the Steppenwolf Theatre Company, which Gary co-founded, and she made her mark in television as well. She appeared in shows like “Karen Sisco,” “The Equalizer,” and “Crime Story.”

She eventually stepped back from acting to focus on her family and philanthropic endeavors. In 2011, she joined the board of directors for the Gary Sinise Foundation.

Gary and Moira’s partnership, spanning over 40 years, became a cornerstone of their resilience as a family. Reflecting on their long marriage, Gary credited their shared sense of humor for keeping their bond strong.

“My wife’s a loving, funny, Irish-spirited person, and I’m still surprised at some of the things she says. She makes me laugh every day,” he. Sadly, Moira and Mac’s battle against cancer consumed much of Gary’s energy.

To make matters worse, Gary’s father had recently suffered a stroke, leaving his mother in need of care. Faced with so many personal battles, he realized his priorities needed to shift. “[…] I kind of had my hands full,” the actorin an interview.

Fortunately, Moira’s journey ended with a victory as she went into remission and became cancer-free. However, their son’s fight was far more challenging. Mac’s condition steadily worsened, leaving him increasingly disabled.

“Our son was fighting this cancer with no cure,” Gary. “Trying to find drugs and doctors or anybody that could do anything for him was like a full-time job. Plus, he became more and more disabled by the cancer as time went on. He needed more and more care.”

Despite the overwhelming circumstances, the actor remained committed to being by his family’s side. His dedication led him to put his acting career on hold indefinitely. “I had to stop traveling away from my family while their lives were on the line,” he.

Then, earlier this year, Gary faced an unimaginable loss when Mac passed away at 33 after his long battle with chordoma. The tragedy left an indelible mark on the family, but Gary found solace in sharing hismusic with the world.

Before his passing, Mac had recorded a full album, “Resurrection & Revival: Part 2,” which was posthumously released on November 10 — a date that would have marked his 34th birthday. “This has been a real labor of very deep love,” Gary.

“Because a lot of this music, I was not even aware that he had it until I discovered it on…his files,” he. Mac, a graduate of USC Thornton School of Music, had a deep passion for drumming, composition, and songwriting.

Despite his physical challenges, which eventually left him unable to play instruments like the drums or piano, he continued to create remarkable music. He also collaborated with his father on several performances.

Gary spoke fondly of their time together,, “He’s just an exceptional drummer. He’s really solid, so solid, and it was always so much fun to play with him…he just had a natural talent.”

In addition to his musical pursuits, Mac served as the assistant manager of education and outreach for the Gary Sinise Foundation. He stepped down in 2020 to focus on his health, undergoing extensive rehabilitation and preparing for a fifth spinal surgery.

Gary reflected on the beauty of Mac’s work, noting how his son contributed music for films, documentaries, and even his father’s charity.

“I will say this about Mac and the album that he made last year — he had achieved something that he set out to do, which was to record all this music in May and make a full album of it…that gave me a lot of joy…just watching him kind of enjoy those moments,” he.
