 Like Brooklyn's Italian and Jewish street gangs of Brownsville and Ocean Hill, the Forty-Two Gang serves as a "farm team" for future members of the Chicago Outfit.
 Forty-Two gang members include future syndicate members Sam "Teets" Battaglia, Louis "Cockeyed Louie" Fratto (also known as Lew Farrell), Felix Alderisio ("Milwaukee Phil"), Samuel DeStefano ("Mad Sam"), Charles "Chuckie" Nicoletti, Fiore "Fifi" Buccieri, Albert Frabotta, William "Smokes" Aloisio, Frank "Skids" Caruso, William Daddano ("Willie Potatoes"), Joe Caesar DiVarco, Rocco Potenza, Leonard Gianola, Vincent Inserro and brothers Leonard, Marcello Giovanni Caifano ("John Marshall"), Mario DeStefano, Bruno Tassione, and Joey "Cowboy" Miletta.
Francis John Schweihs (February 7, 1932 – July 23, 2008), aka "Frank the German", was an American gangster, who worked for The Outfit, the organized crime family of Chicago.
 At the time of his death, federal prosecutors planned to indict him for numerous crimes, including murder.
 It is believed he had participated in, or had knowledge of, many murders going back decades, including brothers Anthony "Tony the Ant" Spilotro and Michael Spilotro, Allen Dorfman of the Teamsters Union, a disgraced Chicago cop, Outfit associate and informant Dick Cain, Outfit boss Salvatore "Sam," "Mooney" Giancana, loanshark Sam "Mad Sam" DeStefano, Outfit hitman Charles "Chuckie" Nicoletti and others.
Cal Neva Resort & Casino, previously known as the Calneva Resort, Cal-Neva Lodge, is a resort and casino straddling the border between Nevada and California on the shores of Lake Tahoe.
 The original building was constructed in 1926, and became famous when the national media picked up a story about actress Clara Bow cancelling checks she owed to the Cal Neva worth $13,000 in 1930.
 After a fire, the building burnt down in 1937 and was rebuilt over the course of 30 days.
 In 1960, entertainer Frank Sinatra purchased the Resort alongside Dean Martin and Chicago mobster Sam Giancana.

 After refusing to pay, "street tax," to the Chicago Outfit, Roe fatally shot a made man who had been ordered to assassinate him.
 In retaliation, Teddy Roe was murdered by an Outfit crew commanded by Sam Giancana on August 4, 1952.

 He is often cited as one of the most influential and skilled MCs of all time, and a pioneer of mafioso rap/street/hardcore content and multisyllabic rhyming.
 On his album "The Giancana Story", he stated that the "G" in his name stands for "Giancana" (after the mobster Sam Giancana), but on other occasions he has stated that it stands for "Genius".
