Premise: Wyatt Earp . He is often regarded as the central figure in the shootout in Tombstone , although his brother Virgil was Tombstone city marshal and Deputy U.S. Marshal that day , and had far more experience as a sheriff , constable , marshal , and soldier in combat . In 1876 , he followed his brother James to Dodge City , Kansas , where he became an assistant city marshal . He left Dodge City in 1879 and moved to Tombstone with his brothers James and Virgil , where a silver boom was underway .
Hypothesis: Wyatt Earp only has sisters.
