THE CORRECT ANSWER:

With the exception of Anthony Anastasio the other four mafiosi all resided on Staten Island over the years but only used the area as a "bedroom community." Each man was primarily active in the other boroughs.

Born in 1892, the man who was arguably the most powerful mobster on Staten Island for decades was Mangano/Anastasia "capo di decina" Alexander (The Ox) DiBrizzi.

Together with his three nephews, the notorious D'Alessio brothers, "Alex the Ox" controlled most of the more prominent rackets including ironclad control over the S.I. waterfront piers through International Longshoremen's Union Local #920 based in the Stapleton section. He also controlled bookmaking, numbers, jukebox and coin-vending machine rackets, and cargo theft.
