I also have a Will of William Epperson. He is my GGG Grandfather. I do not know for sure where he is buried. But you can check New Providence Presbyterian Church at Stoney Point, Surgoinsville ,Tn.Any other cemetery around Surgoinsville, New Canton and maybe the Highland Cemetery in Rogersville. William died shortly after the Will was made in Dec.1823. Sorry ,this is all I can tell you for now.
