It could be spelled Carey, but I've seen it both ways. He had a son named Richard Cary Etheridge in b. 1859 and he had son named Norman Cary Etheridge who had a son named Norman Cary Etheridge Jr (my father) and then me, Cary G Etheridge.
I've been stumped for several years and can't get past Cary. The census records kind of point to Caleb Etheridge with a brother named Jefferson, but no sure.
