Russell "Slim Gray" Gibson (died January 8, 1935) was an American bank robber and Depression-era outlaw associated with Alvin Karpis and the Barker Gang during the late 1920s and 1930s.
 Gibson spent much of his early criminal career with the Central Park Gang based in Tulsa, Oklahoma which included the Barkers, Volney Davis, Ray Terrill and other local criminal figures.
 He participated in his first major robbery when he teamed with Neal Merritt and James "Cowboy" Long to rob a bank messenger in Oklahoma City of $75,000.
 Gibson was arrested for this robbery but escaped from county jail prior to his trial.
John or James "Yakey Yake" Brady (1875–September 2, 1904) was an American criminal, the founder and leader of the Yakey Yakes, an independent street gang based in Manhattan, New York at the turn of the 20th century.
 Under his leadership, the gang, which had its base around the Brooklyn Bridge, operated freely within the territory of the Eastman Gang and successfully fought off attempts by both the Eastmans and the Five Points Gang to absorb the Yakey Yakes into either organization.
 Only following Brady's death from tuberculosis did the gang finally disappear.
The Great Northfield Minnesota Raid is a 1972 Technicolor Western film about the James-Younger Gang distributed by Universal Pictures.
 It was directed by Philip Kaufman in a cinéma vérité style and starred Cliff Robertson as Cole Younger, Robert Duvall as Jesse James, Luke Askew as Jim Younger, R. G. Armstrong as Clell Miller, John Pearce as Frank James, and Matt Clark as Bob Younger.

The Aggi Crew were a criminal drug gang based in the St Paul's district of Bristol.
 The name of the gang was taken from the surnames of the founding gang members.

The Bowery Boys were a Nativist, anti-Catholic, and anti-Irish gang based out of the Bowery neighborhood of Manhattan, New York City in the early-mid-19th century.
 In contrast with the Irish immigrant tenement of the Five Points, one of the worst city slums in America, the Bowery was a much more well-off working class community.
 Despite its reputation as one of the most notorious street gangs of New York City at the time, the majority of the Bowery Boys led law-abiding lifestyles for most of the week.
 The gang was made up exclusively of volunteer firemen—though some also worked as tradesmen, mechanics, and butchers (the primary trade of prominent leader William "Bill the Butcher" Poole)—and would fight rival fire companies over who would extinguish a fire.
 While acting in capacity as a gang (and aided by other Bowery gangs), the Bowery Boys often battled multiple outfits of the infamous Five Points, most notably the Dead Rabbits, with whom they would feud for decades.
 The uniform of a Bowery Boy generally consisted of a stovepipe hat in variable condition, a red shirt, and dark trousers tucked into boots, this style paying homage to their roots as volunteer firemen.
The Shelton Brothers Gang was an early on Prohibition-era bootlegging gang based in southern Illinois.

 In 1950, the "Saturday Evening Post" described the Sheltons as "America's Bloodiest Gang".
 Ancestors of the Shelton Brothers Gang trace their roots back to Ireland, under the surname "Hunter".
 There are still some descendants living in the St. Louis area today.

Thomas Coleman "Cole" Younger (January 15, 1844 – March 21, 1916) was an American Confederate guerrilla during the American Civil War and later an outlaw leader with the James–Younger Gang.
