A small-time Unity mobster who was into "accidental" fires in the early 1900s (e.g. in SillyLoveSongs).

Leo is still infamous within the Family. While his career was flourishing he had a habit of taking jobs and then blackmailing his employers for even more money. But eventually he got too big for his boots and tried to extort the wrong people. He didn't last long then. Went "missing" a long time ago...
