Isabela, Violeta, Alesandra, Elena, Lilia, Anisa, and in the "stupid, but I like it category", Azl, Casandra, Camila, Leyla.

Alexis, Ethan (though it breaks my rule about names being plausible in English and Spanish), Alejandro, Alejo, Jaime, Mauro, Diego. I like the Portuguese version/equivalent of Juan much better.
