Since I posted the message about Anna Deffenbaugh, I unearth some information that explains the relationship between Deffenbaugh and Detwiler. It goes like this: 1. Daniel C. Phillips married Sarah Ann Wood a. Catherine Ann Phillips married George M. Detwiler. b. Lucinda Marie Phillips married Joseph Davidson 15 Aug 1844 1. Anna M. Davidson born 27 Mar 1874 married a Deffenbaugh.
Anna Deffenbaugh is probably their daughter and was probably born in the late 1890's.This doesn't match with your information but it may connect further down the line.Thanks so much for your response.
