Actually, Sarah's name was Eidson, she was married to James Monroe Eidson, son of Wellington Jackson and Mary Louisa McIntosh Eidson.
She and "Roe" are buried in a cemetery beside the old Shanks store in Stanley Valley. The cemetery is, I believe, still there but overgrown.
Sarah and Roe do not have a headstone but two of their children (who died young) do have headstones.
Was Sarah first married to Nathan Hickman and the mother of two sons from that marriage?
