Joe Pesci goodfellas character was based on Tommy Desimone.

We know bits about him in real life but he also had brothers/ relatives in the life.
One is meant to have informed on his gambino pals according to Polisi in Sinatra Club. Which meant Tommy wasn't welcome at the bergen etc

One was called Anthony, who was in the joe dogs book as a pal of Tommy Agro.
Also , I'm half sure I read that one of his relatives was a boss in LA, .

Any info these guys ? Is it even correct?
