Simpson has four living children.
Before O.J. Simpson was granted parole in October 2017, his daughter broke down in tears as she testified on his behalf.
"We just want him to come home, we really do," Arnelle Simpson told the panel.
Arnelle, 50, is the oldest of the former NFL star's children and has a close relationship with her dad, according to Jeffrey Felix, a former corrections officer at Lovelock Correctional Center in Nevada, where Simpson was housed.
She and her younger brother, Jason, 49, stood by their dad during his 1995 trial for the murder of their stepmother, Nicole Brown Simpson, and her friend, Ronald Goldman.
Jason is reportedly works as a chef in Atlanta.
Their mother was Marguerite Whitley, Simpson's first wife. Whitley and Simpson, who met in high school, married in 1967, when she was just 18. They split in 1979.
Simpson went on to have two children with Nicole Brown, whom he married in 1985.
Their oldest, Sydney, is now 33 and graduated from Boston University in 2010 with a degree in sociology. She was spotted in St. Petersburg, Florida, in 2016, where she keeps a very private life.
The youngest Simpson is Justin, 30, now a successful real estate agent based in south Florida.
His company's website states that as someone with "a family immersed in hospitality," he "sets himself apart by dominating customer service and his communication/negotiation skills [that] give his clients the competitive edge."
In 2017, Justin and Sydney attended the funeral of their grandfather, Nicole's dad, Louis.
Simpson had a fifth child, a girl named Aaren, with Whitley in 1977. Aaren was nearly 2 years old when she drowned in the family pool.
Simpson currently lives in Las Vegas, Nevada. Two days before the 25th anniversary of the murders of his ex-wife Nicole Brown Simpson and her friend Ron Goldman, Simpson told the AP that the slayings are "the subject I will never revisit again."
"We don't need to go back and relive the worst day of our lives," he said. "My family and I have moved on to what we call the 'no negative zone.' We focus on the positives."
