History

Settlement in the Aberdeen area began in the colonial era with land patents and plantations tied to Colonial Maryland and the agrarian economy of the Chesapeake Bay. The town’s early growth paralleled the expansion of the Philadelphia, Wilmington and Baltimore Railroad in the 19th century and the rise of nearby ports such as Baltimore.
