Billy Clanton was a rancher and gunfighter who, along with his brothers Ike and Phineas, had several conflicts with Wyatt Earp and Doc Holliday.
In October 1881, Billy and Ike broke Phineas out of gaol, killing Warren Earp in the process.
Billy later took part in the gunfight at the O.K. Corral, where he was shot and killed by Holliday. (TV: The Gunfighters)
