I am still looking for something that would confirm the parents of the Thomas Rock wife Sarah,maybe Parsons. Thomas is on the 1820 census of Giles next to an Elizabeth Rock. I suspect they may be mother and son. Other children of Elizabeth ""may be"" James m Sally Kerr and Nancy who married George Webb. I have no documents any of these are related.There is also a Obeniah Rose who wills land to a Sinny Rock and Elizabeth Rock is to receive rent for Sinney Rock.
Obediah Rose and John Rock are on the 1810 census/tax of Montgomery Co VA. Elizabeth, Thomas and Obediah Rose are near each other on the 1820 Census.
Accorfing to census records Thomas was born ca 1793,John Rock and Elizabeth Snodgrass were married 1792 Botetourt.
Any suggestions would be great, and I'll be happy to share.
