High Ridge Cemetery, in Belmont Country, is on Rt. 214 near Dixon Hill Rd. I have posted many (but not all) of the Giffen / Giffin tombstones. I will continue to add more. Other family names are also located there. It's quite small, if you know of a certain name, I'll look for it, but my first priority is Giffen.
One of the oldest names is George Giffen: b. July 12, 1779 Big Spring, PA d. July 21, 1839 Belmont County
