Jefferson County was created in 1836 as part of Wisconsin Territory and organized in 1839. It was named after Jefferson County, New York, where some of the original settlers of the county originated.
The county is bounded on the north by Dodge County, east by Waukesha, south by Walworth and Rock Counties, and West by Dane. It is four townships wide and four long, and comprehends an area five hundred and twenty-six square miles. The county seat is at Jefferson, on Rock River, at its junction with the Crawfish, and near the center of the county. It was separated from Milwaukee County by an act of the Territorial Council, approved December 7, 1836, set off as a separate town for judicial purposes by an act, approved January 2, 1838, and polls established at the houses of Nathaniel Finch, David H. Sargent and Geo. J. Goodhue.
