Since there isn't much information given regarding Nancy (birth/marriage/etc), I can't tell if the one you listed would be my g-g grandmother.

I've not had a chance to focus too much on this line yet, but I had planned to see if P.W. (I wonder if it would be Phillip West, as a quick search has revealed his name to supposedly be) Austin and Sally Gilbert I was given by another researcher are her parents.

Thank you for checking, and best wishes.
