He definitely wasn't the father of Hank the Bank as he only had that one son, Ambrose. He had a brother named Henry, but I don't know if his brother was Hank the Bank. I don't think so because in one source I found, there was no mention of that and not even in any other articles. But again, I can't be positive. I'll leave that to the other guy who has a much more vast knowledge of things than myself.
