I'm thinking there is some confusion that I might be able to help with. There are multiple Thomas Barnes that are all related but the last two are the applicable ones. Thomas Barnes SR married Mary Andrews and together they had Thomas JR. Thomas JR went on to marry Mary Brockett, the woman hung as a witch, and they had Sarah who married a Scoville, also my relation. After Mary Brockett was hung, Thomas JR married his cousin Mary Andrews, niece to his mother.
