My father's name is Cusano, in Argentina where he was born there are only 4 Cusanos in the phone book and we are all family. Here in America I can see there are many more. Anyway I know from my father that there is a small town on a mountaineous area in the North of Italy, and the town is called :Cusano. So if anybody has any other more info, please let me know, e-mail : email@example.com
Thanks , Daniela.
