I have zero understanding of Italian and Spanish so I have no idea if these are actual last names, but just translated by google:
Italian:
Isabella Ghiaccio (Ice)
Isabella Nevicare (Snow)
Isabella Cielo (Sky)
Isabella Mare (Sea)
Isabella Oceano (Ocean)
Spanish:
Isabella Hielo (Ice)
Isabella Nieve (Snow)
Isabella Cielo (Sky)
Isabella Mar (Sea)
Isabella Océano (Ocean)
Some of them do roll off the tongue, but I got my favourite when I reversed my thinking:
Isabella Caliente
Caliente: adjective, Spanish
hot, warm, heated, horny, randy, spirited
I swear it's not because of the double intender!
