History of Hamilton County
Hamilton County was formed out of White County in 1821. It is named for Alexander Hamilton, Revolutionary War hero and the first United States Secretary of the Treasury. On March 18, 1925, the infamous Tri-State Tornado tore across the county, destroying dozens of homes and farms in Flannigan, Twigg, Mayberry, and Crook townships, and killing 41 people.
