Possibly Samuel Thomas Greene's sister, Sarah Abbott (Greene) Bailey

This tintype is unlabeled. To me, the woman "looks like a Greene" - vaguely resembling Sam and his three brothers. The crude setting also suggests George Frye Greene's amature photography in his North Waterford, Maine, home. Since there are no known pictures of Sarah, this identification is only conjecture. I'm also a poor judge of similarity since I could also make a case for this being a young Caroline Howard. Help!!!!!
