I believe that Harry Mumma's Pennsylvania death certificate,is incorrect in listing his father as Jacob Mumma and his mother as Jennie Boyer. His grandfather was Jacob Mumma and his grandmother was Jane Boyer. Jane died in 1874, so she would not have given birth to Harry. I am certain that Harry was the illegimitate son of Jennie Mumma
