Josephine Sarah Marcus ran away from her home in San Francisco with a friend and joined an acting company touring the country. When they played Tombstone, Arizona, she met Wyatt Earp. They fell deeply in love and were married.
It is true that he did have an extra long barrel pistol. It was given to him and a few others, including Bat Masterson by pulp-fiction writer Ned Buntline, hence the name 'Buntline Special'. It was a Colt. Colt did not use that name until the 1950's when the TV series made it a household name. The foot-long barrels were made until the 1980s.
Wyatt, his brothers, and Doc Holliday went to trial for the famous gunfight at the OK Corral and were acquitted on the grounds of self-defense. The Clantons did not like the verdict and ambushed Wyatt and killed his brother Morgan. After that, Wyatt and Doc Holliday, along with others, raided various hideouts, killing anyone they suspected had a hand in Morgan’s death.
With the law after him for the killings, Wyatt and Josie moved to Gunnison, Colorado. They moved often and invested in mines, and real estate, and operated saloons and gambling parlors in Nome, Alaska, Eagle City, Idaho and others. For a while, they even lived with Josie’s parents in San Francisco. Later, they settled in southern California and raised racehorses and lived off gambling winnings and real estate speculation. In the 1920s, they invested in oil wells.
Wyatt Earp died in 1929 and his wife had his ashes buried in her family plot at the Little Hills of Eternity Cemetery, a Jewish cemetery in Colma, California, just outside of San Francisco. Wyatt Earp was not Jewish, but his wife was. Josie, his wife of fifty years died in 1944, and is buried next to Wyatt.
