The original boundaries of the town correspond to the modern waterfront, Bartlett Street, North Street, and a block east of Norris Street. There were two public town squares. However, in the original deed the town was unnamed, and for several years afterwards in public documents it was referred to as either St. Marys or St. Patrick's, and colloquially as simply "the New Town". Accounts differ regarding the origin of the name itself—some say it is named after the St. Marys River, while others say it comes from a seventeenth-century Spanish mission, Santa Maria, on nearby Amelia Island, Florida. St. Marys was recognized by an act of the Georgia legislature on December 5, 1792, with the result of incorporation in November 1802.
