The Clanton gang was a group of 19th century outlaws that included Ike and Billy Clanton along with Frank and Tom McClaury, and Billy Claiborne. In 1881, a famous gunfight between the Earps and Clantons occurred at the OK Corral in the Arizona city of Tombstone. The event was reenacted in 2268, after pertinent information was pulled from the mind of James T. Kirk, whose ancestors settled the Wild West, by the telepathic Melkots. (TOS: "Spectre of the Gun" )
