looking for ancestry information for my grandfather Leo Zeffield, died Chicago, IL, May 11, 1951. Birthdate I have is July 25, 1899. I do have a SSN as well. Father was possibly Frank, mother possibly named Mary. Leo's siblings (not complete but these I'm certain of): Pauline, Francis, Barney, Mary. Leo was married twice, once to Lillian Schwichtenborg and then to my grandmother Valerie Pasowicz who died August 1978. Leo and Valerie had 5 children. There are many variations of this surname but the one I heard most from my Mother was Zefeldt. She had cousins with that surname.
