There are a number of trees citing Robert Boyd's, d. 1826 in Beaver Co., PA, wife as Sarah Morrison. There is no proof or documentation of Sarah's family's name. The name Morrison for Sarah came into being when I mentioned to a tree owner that the given name Morrison appeared in 2 of Robert Boyd's families and that I was researching that as a possibility for Sarah's family name. Although I was clear that there was no proof and that a lot of research was required to see if it was indeed her family name that tree added Morrison to Sarah and it was picked up by other trees. There is still not one piece of documentation that ties Robert Boyd or his wife Sarah to any Morrison family.
