I often use this very helpful web site when looking for surname distribution in Italy. Do you want to know how common your ancestral name is in Italy? Click here.
The site is in Italian, so if you do not speak or read the language, here is some help:
- Type your ancestral surname into the box on the left under the word “cognome”
- Click the red arrow
- The resulting map shows the distribution of that particular surname in present-day Italy
