Although most Italian names end in vowels, some also end in consonants. Some examples would be Benetton, Basson, Manin, Zanin, Fantin, Marangon, Marras, Perin and Rigonat
Ciao - I just type in some famous names : (Ernesto)Illy, Benetton , Laurentiis, Buffon, Lanz ( and many austrian names in South Tyrol), Gallon , Pelissier ( and many french names from La Riviera region), Cois, Perin, Santon, I've picked up some names from italian football / soccer pages. There are only the endlings of -is , -on in italian.
ALthough most people believe that Italian surnames only end in vowels, many end in consonants, such as Bertin, Besson, Bettin, Bon, Bragadin, Buffon, Garin, Manzin, Manin, Zaccarin, Zamoner, Zampol.
