Thanks for the info, Peter. How can I find out if it was used as in a "local" dialect?

Also, my mother has been tracing her Sicilian roots and she has come across a snag. Her maiden name is Vizzio, but when my youngest brother was in Italy, he was told that it must have been changed from something ...

I have always been told that my last name, Viscariello, is translated as "little butcher" or "little doctor". I know that anything ending in -iello, -ella, or similar means "little" or "small"
