Wyatt Berry Stapp Earp (1848-1929) was a legendary western lawman. He had several brothers, James Earp (1841-1926), Virgil Earp (1843-1905), Morgan Earp (1851-1882), Warren Earp (1855-1900), and half brother Newton Earp (1837-1928).
He left Dodge City in 1879 and moved to Tombstone with his brothers James and Virgil, where a silver boom was underway. There, the Earps clashed with a loose federation of outlaws known as the Cowboys. Wyatt, Virgil, and their younger brother Morgan held various law enforcement positions that put them in conflict with Tom and Frank McLaury, and Ike and Billy Clanton, who threatened on several occasions to kill the Earps. The conflict escalated over the next year, culminating on October 26, 1881 in the Gunfight at the O.K. Corral, in which the Earps and Holliday killed three of the Cowboys.
In the next five months, Virgil was ambushed and maimed, and Morgan was assassinated. Pursuing a vendetta, Wyatt, his brother Warren, Holliday, and others formed a federal posse that killed three of the Cowboys whom they thought responsible. Wyatt was never wounded in any of the gunfights, unlike his brothers Virgil and James or Doc Holliday, which only added to his mystique after his death.
Earp married Urilla Sutherland in January 1870 in Lamar, Missouri, and she was about to give birth to their first child when she died of typhus a few months after they were married. He was arrested in 1872 aboard a floating brothel he owned named the Beardstown Gunboat with a woman named Sally Heckell. She called herself Wyatt Earp's wife. In 1878 or soon after, while in Dodge City, he began a relationship with a prostitute named Cecilia Ann "Mattie" Blaylock. She was his companion until he left Tombstone after the Gunfight at the OK Corral. She waited for him to summon her to join him, but he never did. Instead, the joined Josephine Sarah "Josie" Marcus in San Francisco, and they lived together until his death in 1929.
