Cumberland Island, in the southeastern United States, is the largest of the Sea Islands of Georgia. The long-staple Sea Island cotton was first grown here by a local family, the Millers, who helped Eli Whitney develop the cotton gin. With its unusual range of wildlife, the island has been declared a National Seashore. Little Cumberland Island is connected to the main island by a marsh.
