Thomas, I don't have anything on Peter's parents, but I have this on the parents, etc. of Mary, whose full maiden name was Mary Ann Saylor: Mary was the daughter of Samuel Saylor (1 Sep 1822 - 12 Jan 1907) and Susanna Keith (18 Mar 1824 - 9 Nov 1905). Samuel's parents were Matthias Saylor (1791 - 10 Jan 1861) and Elizabeth Pheasant (1794 - 1888). Matthias's parents were John Saylor (18 Mar 1755 - 1797, baptized Johannes Seyler in the Frederick, MD German Evangelical Reformed Church) and Mary Swope (1770 - 1839). John's parents were Matthias Saylor or Seiler (1720s, Germany - 1785, Hagerstown, MD) and Magdalenda Harry or Herre (1720, Germany - 19 May 1806).
