A few years ago, i discovered and visited a ancestrial cemetery in Armstrong County, Pa. My ancestors, Daniel Keppel (d.1824) and his wife Elizabeth Yerian (d.1821); are buried there, also Elizabeth's father, George Yearian (1733-1804) is buried there also. I am descended from Daniel and Elizabeth's dau. Susannah Keppel (1795-1864) and her husband Micheal Hawk (1788-1856). They went to Clarion Co., Pa.
This Cemterey has dozens of sunken graves that are not marked with headstones.
The following is a listing that i believe was compiled, probably in the 1950's:
