William Stephen Hamilton (August 4, 1797 – October 9, 1850), a son of Alexander Hamilton and Elizabeth Schuyler Hamilton, was a politician and miner who lived much of his life in the U.S. state of Illinois and territorial Wisconsin. Hamilton was born in New York, where he attended the United States Military Academy before he resigned and moved to Illinois in 1817. In Illinois he lived in Springfield and Peoria and eventually migrated to the lead-mining region of southern Wisconsin and established Hamilton's Diggings at present-day Wiota. Hamilton served in various political offices and as a commander in two Midwest Indian Wars. In 1849 he moved to California on the heels of the California Gold Rush. He died in Sacramento, most likely of cholera, in October 1850.
