Jim --

Best information available places this small lot behind the Poyntor Home in Mount Hebron. Of course no way of knowing whether the home still exists or not. According to the census, a man named Walker Pointer lived here some decades ago.

Old Mount Hebron existed at the intersection of county roads 125 and 128, on 39 SW of Clinton. New Hebron is further west on 39.
Here's a map of "Hill Cemetery" on 39 near New Hebron.
