Buckey O'Neill

'''William Owen "Buckey" O'Neill''' (February 2, 1860 – July 1, 1898) was a sheriff, newspaper editor, miner, politician, Georgist, gambler and lawyer, mainly in Arizona. His nickname came from his tendency to "buck the tiger" (play contrary to the odds) at faro or other card games. He later became a captain in Theodore Roosevelt's Rough Riders, and died in battle.
