Yeah, one of the major differences between the real life’s NJ family and the Sopranos is that, on the show, most of the guys were of Neapolitan/Campanian origin, or overall non-Sicilians (Silvio Dante’s people were Calabrians and Patsy’s heritage is Apulian) while the DeCavs are mostly Sicilian. This factor was never mention in the many “Facts vs Fiction” articles and blog entries about the series.
