History

Formed in 1853 from Navarro County

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

Hill County was created from Navarro County on February 7, 1853, and was fully organized on May 14, 1853. The county lost territory to Johnson in 1854 with its creation, lost more land to Parker in 1855, gained land from Navarro in 1858, and lost a small area to Johnson again in 1881.

Boundary changes from the Newberry Library, Atlas of Historical County Boundaries.
