From Pencader Hundred shipping was possible by either the Delaware River or the Chesapeake Bay.
One third of the population of the United States now lives within a day's drive of Pencader Hundred.
The shortest distance overland between the Delaware River Watershed and the Chesapeake Bay was through Pencader hundred which made this area the hub of Mid-Atlantic travel.
The Native Americans used the rivers in the two watersheds to travel from the Piedmont to the Costal Plain for food gathering and the trading of furs and materials such as jasper from Iron Hill. Their trails passed through Pencader.
As European settlements grew into cities, Pencader remained a center point, lying midway between Philadelphia and Baltimore. new York and Washington, Boston and Richmond. Thus, travelers between these early urban centers passed through the area on their way to and from these early centers of commerce. Much of today's commerce follows the same early routes.Right ColumnFall Line
