Sam:
Again I am asking Harrison Swancy Long's dates. Tho' perhaps related, he was NOT a son of John Read Long 1754-1819, will Abbeville, S.C. The Harrison Long who WAS a son of John Read Long died, without wife or children, in Abbeville prior to his estate administration Oct. 4,1830. However, Lucy Long Swancy's (d. before 1819) brother, Harrison Long, son of John Read, had two brothers Reuben and Nicholas, who could have been your Harrison Swancy Long's father. I have never seen or found any records for either of them, so I am no help there. Their Uncle Gabriel Long (Rev.Soldier) younger brother of John Read, went to AL. with others from Abbeville, and resided in Greene Co. His area became Hale Co. just before he died. He is buried there.
Hoping this helps your search,
Bettye Bennett Speed (John Read Long , my 4th great grandf.)
