Both the areas of Somerset and Worcester Counties were divided into old colonial divisions of "hundreds", from south to north: Mattapony, Pocomoke, Boquetenorton, Wicomico, and Baltimore Hundreds. Later subdivisions of these hundreds added Pitts Creek, Acquango, Queponco, and Buckingham & Worcester Hundreds, all of which in turn eventually became election districts for the newly independent state following American independence.
