History

Founded in 1686

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

West New Jersey created the court of Gloucester in 1686, later converting it to a county in 1694 and gaining territory from Cape May. After New Jersey became a royal province in 1702, Gloucester County's boundaries were clarified by 1710, ending the Indefinite Counties Area. The county experienced multiple boundary changes over the following centuries, losing territory to the creation of Atlantic and Camden counties, and gaining and losing areas through various adjustments through 1931.

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