Yay for facts and figures, but I can't really find what I'm looking for.
I need a plausible reason that a Jewish woman in Texas in the 1950s would vehemently hide the fact that she is Jewish, and keep hiding it for the next couple of decades except among other Jews. My current idea is some combination of being a Holocaust survivor who spent time in hiding, and later in TX having lost her job (right now I have her as a nurse, but it could really be any job a woman would have had in those days) because of her religion. If it matters, I have her as Orthodox right now, but it doesn't really matter as long it would make sense for her to keep Kosher and be observant of not working on the sabbath.
Any help would be greatly appreciated.
