I will add some to this lost:

Joe Bonanno: a lesser version of Frank Costello as it comes to business smarts, became the youngest boss ever of one of the most powerful crime families in the United States

Paul Ricca: ran the Outfit, and possibly its ultimate top boss

Joe Massino: brought the Bonannos back from ruins, one of the few who felt Pistone was no good, outsmarted the cops for a long time

Santo Trafficante: ran Florida for 40 years and was after Lansky the most powerful mobster in Cuba

Carlos Marcello: ran Louisiana for 50 years and could have organized the JFK assassination

Johnny Torrio: laid the foundation of the Outfit, became a senior advisor to Lucky Luciano

Vincent Alo: business partner to Meyer Lansky for 50 years

Russel Bufalino: ran a tight-knit family but was a very influential crime figure, organized the killing of Jimmy Hoffa

Frank Rosenthal: probably one of the best gamblers ever, great business sense and very innovative when it came to running a casino

Moe Dalitz: mister Las Vegas himself, managed to become one of Nevada's most respected businessmen while being a gangster

Anthony Scotto: became a union president, had many powerful political connections while secretely being caporegime in the Gambino crime family

John Roselli: had powerful political connections, worked with the CIA on the plot to kill Castro and could have been involved in the assassination of JFK

Murray Humpreys: one of the most powerful figures in the Outfit while not even being an Italian
