I have Mathias Shaffer/Schaeffer b abt. 1813 m Mary Merchant, lived in Mercer Co.,Pa. I am wondering if he is the son of Jacob Shaffer b 1775 Germany d 1825 Lawrence, Pa. other children were James Paden Shaffer b 1802 & Abraham b 1812. Jacob's parents were Frederick & Sabina Shaffer b Germany, came to America 1785 on Brig-Lydia from Amsterdam, had 8 children. Mary Merchant is possibly the daughter of John Merchant/Marchand and Phoebe Mellon of Westmoreland Co., Pa. Anyone have info on her? Thanks, Sue Bowman
