This photo is captioned Abbie Dunham. Amos Osborne’s sister. Those are great clues to have both her maiden and married surnames. I was able to find her profile on FamilySearch.org where it says she was born in 1842 at Hoosick, Rensselaer, New York. I’m messaging one of the contributors to her profile who shares the same last name with her. Hoping this is a quick return!
