Fairfax County History
Fairfax County was formed in 1742, from the northern part of Prince William County. It was named for Thomas Fairfax, the 6th Lord Fairfax of Cameron, proprietor of the Northern Neck. The oldest settlements in Fairfax County were located along the Potomac River. George Washington Settled in Fairfax County and built his home, Mount Vernon, facing the river.
The home of George Mason, Gunston hall, is located nearby. Modern Fort Belvoir is partly located on the estate of Belvoir Manor, built by William Fairfax, along the Potomac. The only member of British nobility to ever reside in the colonies, Thomas Fairfax, lived at Belvoir before he moved to the Shenandoah Valley. The Belvoir mansion was destroyed by fire right after the Revolutionary War in 1783.
Located near Washington D C, Fairfax County was important in the Civil War. The Battle of Chantilly, or Ox Hill, during the same campaign as the 2nd Battle of Bull Run, was fought in this county. Bull Run is located on the border between Fairfax and Prince William County. For most of the Civil War, Union troops occupied the county although the majority of the people remained sympathetic to the Confederacy.

A portion of Fairfax County is named "Alexandria", and is under the jurisdiction of Fairfax County; the city is sometimes referred to as the City of Alexandria or Alexandria City to avoid confusion with Alexandria county.
Neighborhoods in Alexandria include Old Town, Eisenhower Valley, Rosemont, The Berg, Parker-Gray, Del Ray, Arlandria, West End, and North Ridge. Many neighborhoods and cities outside of the Alexandria city limits, including Hollin Hills, Franconia, Groveton, Hybla Valley, Huntington, Belle Haven, Mount Vernon, Fort Hunt, Engleside, Burgundy Village, Waynewood, Wilton Woods, Rose Hill, Virginia Hills, Hayfield, and Kingstowne use an Alexandria address. These areas are actually part of Fairfax County, not the City of Alexandria. Many locals refer to the non-City-of-Alexandria area that has an Alexandria zip code as "Lower Alexandria" or "South Alexandria"; it may also sometimes be called "Alexandria, Fairfax County" [source: wikipedia.org]
