Louis Tom Dragna was born on July 18, 1920 in Los Angeles, California to father Tom Dragna. He has a younger brother, Frank Paul Dragna (nicknamed "Two Eyes" to distinguish him from his cousin who had the same name and had a glass eye). They are second generation immigrants and Louis was the only younger Dragna to be heavily involved in the Mafia. His grandparents Francesco Paolo Dragna and Anna Dragna immigrated to the United States on November 18, 1898, but returned to Sicily 10 years later. His family then returned to New York City in the 1910s and made their way West to California. In 1931 his uncle Jack Dragna became Boss of the Los Angeles crime family and named Tom his Consigliere.
