Check your Watonwan County registration.

In 1849, the new territorial legislature of the recently organized Minnesota Territory authorized the creation of nine large counties across the Territory. Four years later, in 1853, one of those original counties of Dakota, had a large area separated and partitioned off to create Blue Earth County. Only two years later, by 1855, the western part of Blue Earth was then partitioned to create Brown County. Five years later, on February 25, 1860, the southern part of Brown was partitioned to create the county of Watanwan, with the town of Madelia as the original designated county seat.
