Hi, Billie, thanks so much for the info. I think there are a couple of possibilities.
I hadn't posted a name for her as my ggrandfather, Abraham Forsythe's, obit. just listed her as "Miss Westlake," but I think I have other family papers, which I cannot lay my hands on right now, which list her as "Mary." They married on 28 April, 1862 in Greene, VA. So, I will try to find more from that angle, too.
