Pancoast's Mill was owned by Ambrose Pancoast. His wife was Rebecca Pancoast. I don't know if they were related to William Pancoast. I also don't know exactly when they lived... but they are buried in the nearby Friendship M.E. Church, so that info could likely be procured with a road trip.I think the JM 1742 is an actual real time date when Mathis bought the land.The WP 1700 date I believe was back dated possibly to when Pancoast bought it???? There is a Pancoast Mill down near Ricland.Wonder if it is the same person? Might be more stones in Deep Run swamp???
