The James–Younger Gang was a notable 19th-century gang of American outlaws that included Jesse James.
The gang was centered in the state of Missouri, the home of most of the members. Membership fluctuated from robbery to robbery, as the outlaws' raids were usually separated by many months. At various times, it included the Younger brothers (Cole, Jim, John, and Bob), the James brothers (the notorious Jesse James and his brother Frank), John Jarrett (married to Cole's sister Josie), Arthur McCoy, George Shepard, Oliver Shepard, William McDaniel, Tom McDaniel, Clell Miller, Charlie Pitts (born Samuel A. Wells), and Bill Chadwell (alias Bill Stiles). Contrary to frequent reports, the James brothers and Younger brothers were not related by blood.
The James–Younger Gang had its origins in a group of Confederate bushwhackers who fought in the bitter partisan fighting that wracked the state of Missouri during the American Civil War. After the war, the men fought on, though it did not truly become the "James–Younger Gang" until 1868 at the earliest, when the authorities first named Cole Younger, John Jarrett, Arthur McCoy, George Shepard and Oliver Shepard as suspects in the robbery of the Nimrod Long bank in Russellville, Kentucky. The gang dissolved in 1876, after the capture of the Younger brothers in Minnesota during the ill-fated attempt to rob the Northfield First National Bank. Three years later, Jesse James organized a new gang, including Clell Miller's brother Ed and the Ford brothers (Robert and Charles), and renewed his criminal career. This career came to an end in 1882 when Robert Ford shot James from behind, killing him. During the gang's period of activity, it robbed banks, trains, and stagecoaches in Missouri, Kentucky, Iowa, Texas, Arkansas, Kansas, and West Virginia.
