My Hartsock line (and all variations of spelling included) was from the area of Washington Co., PA., and W.VA. I have David Hartsock b. 1798 & Mary Sook/Zook/Cook b. 1797 marrying in Wash. Co., Pa in 1819. We're not sure who David's parents were, but their is a possibility that it was Henry Hartsock and Susannah who lived in Bethleham Twp., Wash. Co., PA.
