Laura Bullion, Pard to Butch Cassidy and the Sundance Kid

Members of the Wild Bunch nicknamed Laura Bullion "Della Rose", a name she came by after meeting Kid Curry's girlfriend Della Moore. Often, Bullion also was referred to as the "Rose of the Wild Bunch". When her boyfriend Ben Kilpatrick and she fled east to evade the law after a train robbery in 1901, the couple traveled under the names "Mr. and Mrs. Benjamin Arnold".[7]

In an arrest report following the train robbery, dated November 6, 1901, Bullion's name is filed as "Della Rose" and her aliases are stated to be "Clara Hays" and "Laura Casey and [Laura] Bullion". The arrest report lists her profession as prostitute.[5] According to a New York Times article, she was "masquerading as 'Mrs. Nellie Rose' at the time of her arrest.[8] The same article also mentions the suspicion that she, "disguised as a boy", might have taken part in a train robbery in Montana. The paper cites Chief of Detectives Desmond: "I would'nt [sic] think helping to hold up a train was too much for her. She is cool, shows absolutely no fear, and in male attire would readily pass for a boy. She has a masculine face, and that would give her assurance in her disguise."[8] Instead of "Clara Hays", Bullion also used "Clare Hayes" or "Clara Hayes" as a version of her alias. Other assumed names she used at that time were "Desert Rose", "Wild Bunch Rose", and "Clara Casey".[7]
