I believe Lionel Dahmer was a native of West Allis, WI . He lived with his parents and sister next door to my aunt. When my aunt passed away in 1942 I believe I was baby sitter for Lionel and his sister during the funeral. He would have been 4-6 yrs. old in 1942. His father was my cousin's HS algebra teacher and his mother and my aunt were good friends as neighbors.
