History

Formed in 1856 from Cooke County

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

Jack County was created from Cooke County on August 27, 1856, and named after William Houston Jack and Patrick C. Jack. The county was fully organized on July 4, 1857, and in the following decades experienced numerous boundary adjustments as neighboring counties were created and organized, with several attached to Jack County temporarily for judicial purposes.

Boundary changes from the Newberry Library, Atlas of Historical County Boundaries; the 5 that matter most are shown first.
