I firmly believe that several of the minor characters were composites
Hell, half the characters in the movie are composites.
As far as I have been able to gather "Tommy" played by Joe Pesci is a composite of Tommy DeSimone, a couple of Paul Vario's sons, and Robert "Bobby Cabert" Bisaccia. The Bisaccia characterization was shoehorned in by Pesci (Cabert had nothing to do with Hill, Burke, et al) just because Pesci thought he was funny ("like a clown", I guess).
Another example of a composite is the "Frankie Carbone" character, who is a combo of Paolo LiCastri, Angelo Sepe, and Richard Eaton.
I know too much about this shit. Imagine if I spent this brainpower on something worthwhile?
