Camden County was the second county to be created. Its land was a combination of the Colonial parishes of St. Mary and St. Thomas. The name is a tribute to Charles Pratt, Earl of Camden and a champion of home rule for the colonies. Remains of a Spanish mission, thought to have been erected 200 years before Oglethorpe's arrival, were found on the St. Mary's River in Camden County. Jeffersonton was the first county seat, then the town of St. Marys, and finally Woodbine.
