There was a Mary "Mollie" Wright (born 1840) who married William A. Sandidge/Sandridge (born 1844), and they are buried in Amherst Co., VA in the Asbury Methodist Church cemetery. Also buried there is a Florence Tomlin Sandidge (born 1880)....as well as a set of twin Sandidge infants who died at birth.
I had suspected that the above Mary "Mollie" Wright MIGHT have been a daughter of the William S. Wright and Angeline Tomlin mentioned in your post, but the list of William and Angeline's children that I have seen on the two available "charts" on RootsWeb WorldConnect does not include a daughter who was named "Mary" (but maybe she was simply missed). I don't know, however, just how Florence Tomlin Sandidge was related to William A. Sandidge and Mary "Mollie" Wright (i.e., I don't know for sure if she was their daughter....so the "Tomlin connection" COULD be by some OTHER "connection").
The later/younger man who was named William T. Sandidge/Sandridge in Amherst (married to a Margaret) is shown by some to have been a son of the above William A. Sandidge and Mary "Mollie" Wright, so I wonder if the middle initial stood for "Tomlin" (versus "Thompson," as shown by some reearchers)? Do you have any information on the above Mary "Molly" Wright who married William A. Sandidge/Sandridge? Thanks.
