As colonial settlement moved into the piedmont area from the Tidewater/Chesapeake area, There was some uncertainty as to the exact tax boundaries of Virginia land versus the Land patent quit-rent rights held by Thomas Fairfax, 6th Lord Fairfax of Cameron in the Northern Neck Proprietary. When Robert "King" Carter died in 1732, Lord Fairfax read about his vast wealth in The Gentleman's Magazine and decided to settle the matter himself by coming to Virginia. Lord Fairfax travelled to Virginia for the first time between 1735 and 1737 to inspect and protect his lands. He employed a young George Washington (Washington's first employment) to survey his lands lying west of the Blue Ridge. Once this legal battle was ironed out, Frederick County, Virginia was founded in 1743 and the "Frederick Town" settlements there became a fourth city charter in Virginia, now known as Winchester, Virginia in February 1752.
