Part of the Waldo Patent, it was called the Lower Plantation of St. Georges, once extending across both sides of the St. George River. It was first permanently settled in 1733 with Scots and Irish immigrants recruited from Ireland by Brigadier-General Samuel Waldo, who offered for each household. Attacks during the French and Indian Wars, however, deterred habitation. A stone blockhouse known as Burton's Fort was built in 1753 by its commander, Captain Benjamin Burton. Hostilities finally ceased in 1759 with the Fall of Quebec. On January 28, 1789, the town was incorporated and named for Thomas Cushing, statesman and lieutenant governor of Massachusetts. On February 7, 1803, the town of St. George was set off and incorporated.
