Unless I'm overlooking or forgetting something, Joey Merlino being the boss, Joe Ligambi being the underboss, and Steve Mazzone being the consigliere are the only things that have been officially confirmed to date. Everything else about the current administration, or who is running things on the street at the moment, is internet speculation.

As for captains, George Borgesi, Anthony Staino, Marty Angelina, and Scoops Licata have all been identified as such in recent indictments. And Mike Lancelotti has been identified as such in several articles in recent years.
