The O'Rourke Brothers were a Hell's Kitchen Irish street gang that operated in the 1920s and 1930s. The gang was led by brothers Willie O'Rourke, Donnie O'Rourke, and Sean O'Rourke. Some of them were hired by mob boss Giuseppe Mariposa as hitmen during the Olive Oil War of 1933-1934, resulting in the near-death of Vito Corleone. However, most of them were killed in city warfare by Sonny Corleone, and Luca Brasi finished the rest off single-handedly.
