Joseph feels kind of like "a Catholic name" to me--of course not as distinctively so as, say, Francis or Anthony or Teresa, but still a little less WASPy than George or John or William.
My nana is Teresa and there's a tradition of Margarets, Bridgets, Batholomews etc. Andrew (my dad's name) wasn't sufficiently Catholic
enough so I got Francis as a middle name. There were two John Paul's at my school.
Saint name exclusivity died out just a few years after I was born, but maybe that's a Scottish thing.
