Because family is at the heart of the Mafia
Tommy Lucchese spent his formative years in a neighborhood dominated by the Morello-Terranova gang of Corleone. At the height of his power, some of the men closest to him were Corleonesi, people who’d worked with Giuseppe Morello, and who Tommy had known and worked with since his teens.
Joseph Gagliano, who was known by the nickname “Pip the Blind,” was called “the mastermind of one of the biggest opium rings in the country” by the assistant district attorney who prosecuted him for narcotics trafficking in 1946.
Some of the most telling of "Capitano" Angelo di Carlo’s associations are those who signed affidavits in support of his release from internment at Fort Missoula in the summer of 1943.
There are three first cousins from Corleone who immigrated to New York around the same time, and had the same name: Stefano la Sala. One would become known as Steve LaSalle, a high-ranking member of the Lucchese crime family for half a century.
