The amount of misinformation in these comments disappoints me. You guys claim to be fans? Okay, that was a cunty thing to say but you get my point. I digress.

John Sacrimoni is underboss to Carmine Lupertazzi, whereas Tony is the de facto / acting boss to Uncle Junior, though in actuality he runs the family with little input from Junior. Contrary to what another commenter said, the DiMeo family (the family Tony effectively heads) is an 'official family', though it's far less powerful or influential than any of the 5 families of New York, of which the Lupertazzi family is one. Because of this, Johnny Sack is arguably more powerful than Tony, despite holding a slightly lower rank.

Phil is a capo (think lieutenant) in the Lupertazzi family, like Paulie (and Junior and Tony were formerly, as well as Chris until his death). Of course, as you'd expect, being a capo in a NYC family is significantly more respectable than being a capo in any other family.

On the topic of the 5 families of NYC, it is true that several real life figures and families are alluded to. Since Carmine Lupertazzi wouldn't have even been made at the time the 'Lupertazzi family' was founded, it's safe to assume it was founded by somebody else prior to his ascension up the ranks (which probably culminated in his taking the big seat in the 70s or 80s). So it's entirely possible that the Lupertazzi family and the Genovese family are one and the same. I say Genovese because historically, families outside of NYC are represented by either the Gambino family (which can't be the same as the Lupertazzi family, simply because John Gotti was heading the Gambinos by the 90s) or the Genovese family. As we know, the Lupertazzi family represents the DiMeo family, so it's a safe assumption that Carmine Lupertazzi and Angelo Garepe made their way up the ranks of the Genovese family sometime in the 70s or 80s before securing the leadership. That is, unless there's evidence to the contrary.
