Dear Leonard, I find an iron worker born about 1868 in Liverpool named Edwin C Pinkham. He reported his age as 51 at Bath ME in the 1920 census. He was married to Mary A Hughes b. Waldoboro, ME in 1874. He probably worked at the Bath Iron Works building ships. If this is the right family the children were Henry D b c 1900 in England d 17 Apr 1982 in Augusta ME; Isabel M. was age 15 in 1920; Eleanor E was age 8 in 1920 and Edwina Dora b 12 Mar 1915 d 13 Aug 1918 in Bath ME. I do not show descendants for any of this family, but hope these names may be helpful. I would appreciate knowing Edwin's ancestry.
