Interesting! I'd be wary of citing Wikipedia as a source for names, though. That link seems to say that Wikizziunariu is a common Sicilian name, meaning "Wikipedia." I think someone is pulling our leg there.
Don't know enough Italian to read what is listed about all of them. Some, like Franciscu and Natali, seem to have close matches to well-known names. Others, I'm less sure of. Calabria is a region of Italy - did not know it was a name. And others, I simply cannot read what is on the page for them.
