I found a Robert Henry Abernethy b. 10/16/1863 d. 3/27/1932 married Margaret Duckworth.His death certificate says he was buried at Hills Chapel UMC Cemetery which is on Hwy. 16, in Lincoln County not far from where the US Census placed him and Margaret Duckworth Abernathy.Charlie R. and Etta are buried at Hills Chapel UMC Cemetery.My list says Charles A. (not R.)Abernathy b. 7/4/1883 but doesn't give a death date and Etta's (Esther?)is b. 10/17/1883 and d. 6/13/1960 (wife)They are buried with John Abernethy d. 9/12/1816 (age 63).I'm presuming R. Henry was related to John to be buried in the same cemetery.Robert Henry's death certificate says he was son of Simon Abernethy and M.A. Armstrong.I will research some more and make sure Charlie and Etta is your family because there are several later Charlie Abernethy/Abernathys that lived in this area.
