There aren't names that are specifically Sicilian or Southern Italian, but there's some names that are much more common in Sicily than elsewhere. Some traditional Italian names tend to be very regionalized.
Very stereotypical Sicilian names are
Calogero and
Rosalia.
Ciro and
Gennaro are used predominantly in the Naples area.
In general, I have the impression that traditional
Marian names like
Carmela,
Concetta,
Assunta are much more common in the South (not only Sicily) than North. However, they aren't common for younger people.
