My wife is related to Boone Helm, the notorious outlaw and cannibal, through her Missouri relatives. And we will often visit his grave at Virginia City, Montana. Best wroiteup on Boone Helm is in the april 1973 True West magazine. Lots of mentions about Helm in Montana history books. My wife, Carol Gilluly, has done some limited research on this creep. Some members of her family refuse to talk about the man. We think the guy is sort of fascinating. Black sheep, indeed, but it's all history.
