Sylvester Davis, the first settler in the township, came to section 20 in the spring of 1855 and built a more permanent dwelling later that fall. The township was officially organized in 1858 and called "Brooklyn." At the first meeting of the township, the people elected a chairman, two supervisors, a clerk, two justices of the peace, a collector, a constable an assessor, a road supervisor and an overseer of the poor. In 1862 the state legislature told the township to change its name because another town had prior claim to it. It was then briefly called Canton but the name had to be changed again for the same reason. In May 1862 the township was named in honor of Senator William Windom of Winona.
