History

Formed in 1803 from Lycoming County and Westmoreland County

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

Indiana County was created on March 30, 1803, from Lycoming and Westmoreland counties, but was not fully organized and remained attached to Westmoreland. Jefferson was attached to Indiana in 1806, and Indiana became fully organized and detached from Westmoreland later that same year. Jefferson was detached from Indiana in 1830, and Indiana gained territory from Cambria and Clearfield in 1855.
