Hi, I'm trying to find Peter's parents. By my research, Peter was born around 1836, and later married Sarah Cordelia (Shoemaker/Schumacher) Hammer. They had several children: Edwin Waugh, Isabella, Milton Elmer, and John. They lived in Maryland for at least the later years of Peter's life, as he retired there. I'm thinking his parents may have immigrated to Baltimore, but it could have been his parents' parents. Thank you in advance.
