Probably not relevant, but I thought I'd chime in anyway.
My Grandfather: Joseph Luckow was born in New Haven CT USA July 9, 1898. He was one of 14 children, most of whom died at childbirth or as kids. His brothers and Sisters that lived were: Frank, Isabelle, Wally, Stella, & Marie (all named Luckow). Near the beginning of the 20th century they moved to a farm in Plymouth, Indiana. Then later, they moved to Chicago Illinois.My parents are Joe Luckow and Betty Luckow (in the Chicago Area)
