Descending from Evil: The Story of Herman Webster Mudgett

Descending from Evil: The Story of Herman Webster Mudgett:

I found this article and interview very interesting.  This is the kind of story I'm after with regard to the Midwest Axeman.  To date I have found only a handful of descendants/relatives of victims and unfortunately, very few of them really know anything about the crimes.  I'm still convinced, that somewhere in the U.S. is a person, or persons, with a family story of a kind of strange uncle or cousin who collected odd nick-knacks like old keys or earrings.  Maybe a hair pin or broken key chain.  A guy who was shy around women and restless at night, possibly pacing around the house.  Anybody have a family story like that, from around the 1920's?
