Does anyone have information on siblings of Isaac Young, Jr. b. c. 1815 SC to Isaac Young, Sr. and an unknown mother in Williamsburg Co. (once Georgetown District), SC? Isaac Young, Sr. was born sometime before 1774 in an unknown location. In the 1800 census, there was one young male child and an adult woman in the Isaac Young, Sr.'s household that are both unidentified, so far. The boy could be a sibling or half-sibling of Isaac Young, Jr. and the woman could be his mother. The household does not appear in the 1810 census, but does appear in the 1820 census. In this census, there are several children in the household, most of whom could be Isaac Young, Jr.'s step-siblings. The child shown in the 1800 census would have been over 20 and most likely on his own. I am also seeking information on Isaac Young, Sr.'s last wife, Martha and her children. Any information on this family would be greatly appreciated. Melanie Y.
