I'd think her mother or father was once Jewish and converted to Catholicism. Pretty hard for me to picture on someone who isn't Orthodox Jewish, as it's a name that's been ingrained in the culture for centuries. It's actually in the top 100 in New Jersey, I'm guessing because of the high Orthodox Jewish population in some areas here. I often pass a private Jewish elementary school with the name
Rivka in it.
That being said, it technically is no different than using Rebecca/Rebekah. Interesting that the original versions of Hebrew names like
Rivka,
Eitan, or
Elisheva are usually used exclusively on Jewish children, yet it's "okay" to use the English
Rebecca,
Ethan, and
Elizabeth on
Christian children.
I have this struggle with
Shoshana myself.
