Fighters who is the relative of entertainers

[scorpio83]

I know that Max Baer's son played Jethro in the Beverly Hillbillies TV show. What I discovered on the PBS show called "Finding Your Roots" Season 3 Episode 7 "Family Reunion" that LL Cool J's biological material grand-father is Christy Lewis, who was the brother of former World Light Heavyweight Champion John Henry Lewis which made him LL Cool J's great-uncle. Can anyone please add the information in the biography of John Henry Lewis? Also, can you find out any great fighters who is the relative of entertainers?

John Goodman's brother in law was a Boxer. I don't remember his name though.

John Goodman's brother in law was a Boxer. I don't remember his name though.

It was Goodman's wife Anna Beth Hartzog's brother who was the boxer - making him Goodman's brother in law as you said.

Pretty sure he was Preston Hartzog, who had a pro record of 15-1-1, and died at the young age of 29 of some obscure disease?
