History
Formed in 1852 from Door County and Manitowoc County
An old deed may name a county that no longer exists, or a boundary that has since moved.
Kewaunee County was created from Door County on April 16, 1852, but initially remained attached to Manitowoc County for judicial purposes. The county became fully organized and was detached from Manitowoc County on January 1, 1859.
