History of Madison County

Madison County was formed on January 13, 1846. It has been self-governed since 1849. It was named after James Madison (1751–1836), the fourth President of the United States (between 1809 and 1817). Hiram Hurst was the first European-American settler in Madison County, having come from Missouri about April 15, 1846.
