I have his father George Samuel Baugher born 7/20/1818 in
E. Berlin, Adams County, Pennsylvania so I assume that John David was born in the USA, although I have no place of birth for him.
His grandfather George William Baugher born 1/14/1784 in E. Berlin, Adams County, Pennsylvania
His great-grandfather John George William Baugher born 4/15/1750 in Simmern, Hessen-Nassau, Germany.
