Looking for info on Spencer BOBO who lived in or around Fredericksburg around 1750-1775 or thereabouts and had two children, John BRUCE and his sister Martha BRUCE bound to him in the 1750s. Parents of John and Martha were John BRUCE and Margaret FRAZIER. John BRUCE (the son) was born ca 1744 and both John and Martha were "small children" in 1752 when John, the father died.
