History

Formed in 1772 from Frederick County

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

Berkeley County was created by Virginia from Frederick County in 1772 and named after Norborne Berkeley, 4th Baron Botetourt. The county lost territory to the creation of Jefferson County in 1801 and Morgan County in 1820. Berkeley County separated from Virginia on August 5, 1863, and became a county in West Virginia.
