Many different ethnicities settled in italy over the years and some surnames reflect that. Persico (means Persian), Tedeschi/Tedesco (means German), Greco (duh), Mormando (means Norman)
Oh wow, that's really interesting, thanks for that. "Tedesco" looks like it is probably cognate with words like "Teuton", "Deutsch", and "Dutch".
No one is really sure where it came from originally, but one theory has it that the word "Mafia" itself might be a leftover Arabic word.
