The Genna crime family (Italian pronunciation: [ˈdʒɛnna]), was a crime family that operated in Prohibition-era Chicago. From 1921 to 1925, the family was headed by the six Genna brothers, known as the Terrible Gennas.[1] The brothers were Sicilians from the town of Marsala and operated from Chicago's Little Italy and maintained control over the Unione Siciliana.[1] They were allies with fellow Italian gang the Chicago Outfit. After a bloody war led to their demise in the 1920s, the gang was eventually absorbed by the Chicago Outfit.
