The area gets its name from the Atlantic Transport Company, though other possible derivations have been offered, one of which is from the Indian word for "Land of many deer." The Atlantic Transport Company of West Virginia placed a major order with the New York Shipbuilding Corporation of Camden, New Jersey for four big ships launched 1902-3, which may have something to do with the choice of the name Atco at this time.
