RE: Joey M. I read that he "made" Ralph N at soldier level and then promoted him to boss. Is that legitimate?
It was rather unorthodox but yes.
Yes.
If so, was Stanfa recognized by the NYC 5?
Yes. And he had the backing of the Gambinos to assume the boss position in Philadelphia.
Point is; aside from his dad and uncle being made, is Joey M for real, made LCN? Or is he part of a gang?
Merlino is a legit made (LCN) guy.
Would anyone outside of Philly introduce him as a "friend of theirs" ?
If by "friend of their's," you mean they'd say "He's a friend of ours," yes. Because, as said above, he is a made guy.
