I thought he had at least two children with his first wife. I do remember the interview they had with Connie Chung with her asking in a most tacky way if the two kids--a boy (say in his late teens/early 20's) that said the last time he saw his father was when he was three, and a younger girl who said she remembered nothing about him. Whether he had other kids, I don't know--but perhaps the booze and drugs took away his ability to reproduce.
