Four Great Americans by James Baldwin

George Washington's father owned a large plantation on the western shore of the Potomac River. George's great-grandfather, John Washington, had settled upon it nearly eighty years before, and there the family had dwelt ever since.

This plantation was in Westmoreland county, not quite forty miles above the place where the Potomac flows into Chesapeake Bay. By looking at your map of Virginia, you will see that the river is very broad there.
