| Old Trap | community in S Camden County, was probably settled as early as the 1650s. In the eighteenth century, it was the center of much maritime activity, and a grog shop there supplied the local trade with West India rum. Tradition says that men carrying grain to a local windmill tarried long at the grog shop—it "trapped" them. By the end of the Revolution, the name The Trap was being used, and after 1800 Old Trap came into use. |
