Hi Nan,
Wish I could help. The fact that she was listed as Black could mean just mixed, such as
Seminole. Census takers were not always up on what we consider proper ethnic backgroungs, as we are today. My grandmother was listed as Mulatto on one census, though her lineage, from Ontario, Canada, was
English, Scottish and
German. Now, for surname, I don't know how
Simmons got in there or if this is even the right lady for you but everything else fits. Wish I knew the names of her parents. That would really narrow things down for me, even if just given names and no surnames.
Sue
