Previously, Doug shared insight into his upbringing as the eldest child of John, who was also dad to Andrew McCain, 64, and Sidney McCain, 59, with ex-wife Carol Shepp as well as Meghan, 41, John McCain IV, 39, James McCain, 37, and Bridget McCain, 34, with wife Cindy McCain.

"It was just different, it took some time getting used to," he said in the 2018 documentary John McCain: For Whom The Bell Tolls. "I have a good relationship with Cindy, as do my brother and sister. And I have a good relationship with Meghan, Jack, Jimmy and Bridget. We're not extraordinarily close, but if I ever need something, I know how to reach them."

“We did normal things, you know, that fathers and sons and kids do,” he recalled of his childhood. “The housing we were in was all basically Navy pilots and their families. There were a gazillion kids around, so they tended to kind of rotate in and out because people were always getting transferred. There was just a lot of fun things to do.”

And while Doug was known as a great pilot at the time of his death, he’ll be remembered as an even better family man.

“He was a loyal friend to many and cherished each and every friendship,” the obit read. “He was a devoted son, a loving father to Caroline and Shepp, and most recently found great joy in being Teddy’s grandfather.”

“Doug will be remembered for his generous heart his loyal friendships, and his unwavering love for his family,” it continued. “He will be dearly missed by those close to him.”
