If this helps McCama Martin's wife was a Spencer and daughter of Joshuah Spencer. The Spencers have ties to the Robinsons. I have no doubt your Peggy Martin is related to us just dont know how. Im hoping the Archives has an estate record for Isaac (son of Thomas)which should mention Isaac's children. This will help us eliminate a few people. Now as far as who belonged to Jesse, Moses, and My William will be no way to prove without locating Obituaries or some kind of burial or church record. These 3 martin men died owning nothing so there are no estates or wills to account for all their children.
It's been a while but "I Think" (dont quote me on this) The Bairds came from New Jersey????
