Well, if you are talking about Hank Williams Sr.

There is Hank Jr., Hank the third, two of Hank Jr. daughters, Jett williams, and four or five of cousins and siblings that claim direct heritage to Hank Sr., not to mention the other kids who's mother's make some kind of claim to liniage I think that is a pretty good start. Then you could go through the people who pattern themselves after Hank which are pretty much everywhere you look.
