When I was in high school, Evelyn seemed pretty obscure and underused but somehow it has jumped into the top 25, it's really odd. I work with kids and I have yet to come across either one, but I live in a heavily Hispanic area, so I don't think the popularity lists have had as huge of an effect on my tiny area as it has other places - but popularity DOES matter to me, we don't plan to stay here. I know more male Alexis's than I do Evelyn's, to give you an idea of my area, I think that it makes me less aware of whats popular.
Cordelia is one of our top contenders, it just hasn't been feeling "right" lately, I dunno, maybe I'm just falling out of love with it, I kind of feel bad. Valentina and Wilhelmina are ones I need to write down, though. Josephine / Josephina would be on my list, but it's my step-daughters middle name.
