t is generally thought that Frederick Michael married Catherine Vanderpool in Augusta County, Virginia, but it is possible the marriage took place in Tulpehocken (Palatine) settlement in Pennsylvania. It is believed that Catherine was a daughter of Abraham Vanderpool. About 1743 Frederick and his family migrated to the lower branch of the Potomac, not far from Moorefield in Hampshire County, Virginia. They, along with the Yoakums and Harness'.were among the first settlers of that region.
