Sam Alderman lived in Mountain Grove, Virginia, in Bath Co, after returning from Oregon and I know that Selma's third child, Mary Alice, was born there in 1933. Not sure about the others. I have heard quite a bit about Sam, but no one had mentioned that he spent the rest of his days in a wheelchair. He died at the Pinecrest Sanitarium, in Beckley, WVa, where he was hospitalized for tuberculosis. I've corresponded with one of his daughters.
Sam was a son of William C and Phoebe Jane (Alderman) Alderman, who married in Pocahontas Co, WVa, 12 Jun 1876.
Do you have the names of Selma's parents? I suspect that she was originally from Alleghany or Bath Co, Virginia, but haven't looked there for a marriage.
