William Marion Dalton (1866–June 8, 1894), called Bill Dalton, was an American outlaw in the American Old West. He was the co-leader of the Wild Bunch gang and he was the brother of the founders of the Dalton Gang, Gratton, Bob and Emmett.
Laura Bullion was a female outlaw of the Old West. Most sources indicate Bullion was born of German and Native American heritage. Laura Bullion was a member of Butch Cassidy's Wild Bunch gang; her cohorts were fellow outlaws, including the Sundance Kid, "Black Jack" Ketchum, and Kid Curry. For several years in the 1890s, she was romantically involved with outlaw Ben Kilpatrick ("The Tall Texan"), a bank and train robber and an acquaintance of her father, who had been an outlaw, as well.
