My 3-gr-gf was Eugene Bartlett, who was born somewhere in Mass. on 12 Jul 1854. His death certificate states that his father's name was George Bartlett and his mother was Frances Clark. Did Walter have a twin by any chance? Eugene moved to Chicago sometime before 1874, when he married Lydia Atkinson and became a Chicago police officer. Coincidentally, they named one of their children Walter. Any info would be helpful.
