Exuma was settled in or around 1783 by American colonial loyalists fleeing the Revolutionary War. The expatriates brought a cotton plantation economy to the islands. George Town was named in honour of George III, to whom the settlers maintained their loyalty. A few smaller cays still remain partially or wholly privately owned, albeit they are still referred to as part of the Exuma–Bahamas Cays; they are distinguished by a three-digit suffix number. The best known examples are adjoined cays Exuma 642 and 643, which are suffering from receding shorelines.
