Truro Parish, Virginia

Truro Parish initially covered all of the land north of those rivers up to the Potomac, and westward all the way to the Blue Ridge Mountains at Ashby's Gap.

George Mason, author of the Virginia Articles that presaged the Bill of Rights, was elected to the vestry that year.

His father, Augustine Washington, had served on the vestry for a few years, starting in 1735.

The new boundary was just south of Washington's estate, and the northern portion became Fairfax Parish, with The Falls Church as its seat.

Parishioners of Truro, however, complained that the division was far more favorable to Fairfax Parish, and succeeded in having a new border drawn through Washington's estate, such that Washington was deemed to reside in Truro and he was elected to that vestry.

Drawn over today's civil boundaries, Truro Parish's final incarnation would include the Southern and Southwestern part of Fairfax County.
