Notes:
Henry's marriage to Esther Mumma is discussed on her page. Henry has not been identified in the Hershey family.
There was a Henry Hershey, b. 1786 to Benjamin Hershey and Catherine Landis, but I don't believe this is the same Henry Hershey. That Henry was married to Mary House and they had 12 children. The 1850 census doesn't support that many children to this Henry Hershey.
