In 1767 in Berks Co PA, Jacob m. Ottilla Schmidt, b 1744, dau of Charles Schmidt, b Germany. Jacob and "Tilley" had 12 children, most of whom you will find via St. Mary's, or "The Old Pine Church," near Mt Jackson Va. Mill Creek is basically the land you can see for a long way behind (west) the church. Jacob's last church is a few miles away SW, Solomon's Evangelical Lutheran Church (still there), where his good friend, Rev. Paul Henkle, held his funeral (d 9 May 1815). There are many tombstones in the church grave yard that cannot be read. In the 1990's I talked with the groundskeeper, Mr. Getz, and he had a plot map, but not all tombstones were readable, so many names were missing. He thought their graves were there, nearest the churc.building, with the older graves. firstname.lastname@example.org
