of Harley Hamm and Ethel Davison Hamm. Jerry identified
the man on the right as his grandfather Harley and the
lady on the left as his grandmother Ethel. The two
boys are Jerry's father and his brother (Leonard and
Harold Hamm). Jerry asked if the older man and woman
were Josiah Davison and his second wife Mary Harris
Davison. He also asked for help identifying the other
girls in the photo.
