What stands out about Deal Island’s past

Deal Island was historically known as Deal's, Deil's, and Devil's Island. Nearby Dames Quarters also had an unappealing name: Quarters of the Damned. At least one source also attributes these nicknames to the area's use by pirates.
The island is famous for Joshua Thomas, who predicted the British defeat in the War of 1812. Thomas is buried alongside the Joshua Thomas Chapel.
The Deal Island Historic District, Sea Gull (skipjack), and St. John's Methodist Episcopal Church and Joshua Thomas Chapel are listed on the National Register of Historic Places.
