Defunct counties

• Dane County was renamed in 1840 to the current Christian County.
• The original Knox County, Illinois, became extinct with the formation of the Illinois Territory in 1809 - or, more precisely, it became Knox County, Indiana. The modern Knox County, Illinois was formed much later and was not a part of the original Knox County.
