I recently read a story where a newborn boy was named Apollonius after St. Apollonia, patron of dentists. (The protagonist's parents were dentists, so it was a nod toward both of them.) I'd never use either name, but they've been on my mind since.
I think Apollonia too clunky and OTT for most people, but I still kind of like it. It's very chunky and rolly-polly, the way it bounces off the tongue.
