I do have a copy of the photo of Mary and her daughters, but not one of Emma Jane and her family. Photos are always a treasure to get! My email address is firstname.lastname@example.org if you can scan and email them. I have photos of Charles and Mary's tombstones plus a jpeg photo of the charcole portrate of Charles Rolston. There are also a couple other of Charles and Mary's children I have photos of.
Do you known much about the Ivers family? I'm most curious about the heart problems found in most all the male children of Charles and Mary's. The female members were not affected until the following generation. Since I have a good deal of information on the Rolston side, I'm assuming the genetic condition may have come from the Ivers' side.
