My great great grandfather is Gabriel G. Neff. He is married to Sarah Schrock. Have his date of birth as January 21, 1841 and death August 6, 1911.His death certificate lists his father as Gabriel Neff from PA and his mom Mary Doner/Domer? (hard to read) from VA. Th Census Index (1880) lists his dad as from VA and his mom from PA.I have a picture of their tombstone.and the death certificate of a daughter, Emma L. Maurer, married to Alfred Maurer (my great grandparents).I would like to expand my family tree if anyone has any additional info. Thanks!
