History

Formed in 1817 from Knox County

An old deed may name a county that no longer exists, or a boundary that has since moved.

Daviess County was created from Knox County in 1817. Over the following years, parts of Daviess County were lost to the creation of Owen County in 1819, Martin County in 1820, and Greene County in 1821. The county lost additional territory to Martin County in 1828.
