In 1833, William Smith Wilson, his wife Rebecca, and his brother-in-law Daniel Pearce moved to the area now known as Oswego. The land belonged to the local Potawatomi, Ottawa, and Chippewa tribes, but the United States government removed the Native Americans when the government started surveying the land along the Fox River in Kendall County. In 1842, the federal government placed the land for sale at an established price of $1.25 an acre.
