Love it! I think it's so handsome. I think Cayetana's nice as well, but I tend to prefer more blunt girl names in Spanish like Leonor, Alba and Mar.
I really like Feliciano, but I think that's pretty dated.
Hm, I personally really like (not all of these are under-represented, though. Some are really popular... but popularity does vary a lot by country):
Álvaro
Efraín
Bruno
Feliciano
Gaspar
Gonzalo
Hugo
Julián
Maximiliano (I like Emiliano, too)
Rafael
Sebastián
Yago
Leandro
