Just saw your post. There are two Sentell Tapley entries in the book "Searching For Our Ancestors Among the Gravestones", 2nd Edition, A Cemetery Record of Johnson County, GA.
Oaky Grove Cemetery (About 2 1/2 miles off HWY 319 north of Wrightsville, GA. There is a church sign)

Sentell Tapley b. Jul. 5, 1876d. Jun 28, 1944 --Parents: Jim and Rebecca Page Tapley (also buried at Oaky Grove)
Additional info regarding Jim and Rebecca Page Tapley: Jim Tapley is James Madison Tapley who served in Company F (Battleground Guards) Johnson Co., 48th Regiment Georgia Volunteer Infantry. (Source: For Home and the Southland-A History of the 48th Georgia Infantry Regiment by John Zwemer) He is the son of George Washington Tapley and Elizabeth (UNK) Tapley. Elizabeth Rebecca "Becky" Page married Solomon Horton, then married Jim Tapley. She is the daughter of Solomon and Elizabeth (Scoggins?) Page. (Fed census 1860 Johnson Co., Wrightsville PO--dated June 30th) James Tapley is also listed on that census. Rebecca Page Tapley's death certificate is #24968 GA (Johnson Co.) You can see it at Georgia Archives Virtual Vault. If you need information on Susan Martha Price, she is probably part of the large Price family descended from James Price and Elizabeth Black Price. Hope this helps you.
