This nice looking gentleman could be my great-great grandfather. George Jackson DeHart. (1835-1916)
And then again, it could be someone else.
Another photo in this group, could be his daughter, Carolyn. For some reason, I think she resembles my grandmother, Nina, who would have been Carolyn's niece.
Carolyn was a 1/2 sister to Emma Susan DeHart Borden. They were the daughters of George Jackson DeHart.
And lastly, there is the woman below. Could she be Great-Great Grandpa DeHart's second wife, Carolyn's mother? If so, her name is Sarah Caroline Corey.
