I tried Googling to find out, but it says nothing about his family, so I'm guessing he doesn't have one.
I haven’t found any mention of wife or children, either. Want to read something scary, take a look at this interview of Chambers in Mother Jones. He is an unapologetic racist who looks forward to the day White people are “gotten back.” This is a very evil and deranged individual.
