My Bailey Appleton Dover was born 1817 NC, probably in Buncombe County. His father was born 1793 SC.
There are three known Bailey Dover's, probably all connected and all in Buncombe, NC at the same time. They were born 1791, 1817 and 1830. Best guess is the family was in Pendleton, SC 1800-1810. No clue before then.
