History

Formed in 1820 from Pendleton County

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

Grant County was created from Pendleton County in 1820 and named after John Grant. The county expanded through several boundary adjustments over the 19th century, gaining territory from Harrison, Campbell, Kenton, Owen, and Boone counties, with a brief transfer to and from Gallatin County in 1867 and 1868.
