Towlston Grange is an 18th-century plantation in Great Falls in Fairfax County, Virginia, United States. The estate served as a residence for several prominent members of the Fairfax family. Towlston Grange is located at 1213 Towlston Road in Great Falls. There is a photograph of Bryan Fairfax's Towlston Grange in its unrestored state, taken by "The Rambler" of the Washington, D.C. Evening Star newspaper in 1918, that shows a 1 1⁄2-story clapboarded house built in the English tradition.
William Fairfax acquired several thousand acres on Difficult Run from his cousin Thomas Fairfax, 6th Lord Fairfax of Cameron and named his property Towlston Grange.
William's eldest son George William Fairfax and his wife Sally Fairfax née Cary settled at Towlston Grange after their marriage in 1759.
Bryan Fairfax lived at Towlston Grange from 1768 until 1790. Bryan was given Towlston Grange with its adjacent 5,500 acres (22 km2) Towlston Manor in his father William's will.
I also give bequeath and devise unto my Son Bryan and his Heirs for Ever all my Tract of Land near and below Difficult Run in the aforesaid County containing about Five thousand five hundred Acres together with the House, Edifices, Stock and Appurtenances thereon known and calld in my Deed by the Name of Towlston Grange, and likewise give and bequeath unto my said Son Bryan and his Heirs for Ever my Negroes now employd thereon named Pipero, Punch, Adam, Old Sarah and her Daughter Betty and their Issue, Omah and her Children Scipio, Sarah, Dolly & their Issue also my waiting Boy Jack lately purchased of Mr. Amblery.
His friend George Washington and Martha Washington traveled to Towlston Grange to stand as godparents for Bryan's third son, Fedinando. Fairfax sold Towlston Grange to George Washington for £82.10. He moved to Mount Eagle (plantation), (south of Hunting Creek, and Alexandria), where he lived from 1790, until his death. Upon the death of his cousin Robert Fairfax, 7th Lord Fairfax of Cameron in 1793, Bryan inherited the title of eighth Lord Fairfax of Cameron.
"Bryan Fairfax inherited Towlston Manor in 1757 upon the death of his father, William Fairfax, cousin of Thomas, Lord Fairfax, for whom Fairfax County was named. Lord Fairfax later gave him the adjoining Great Falls Manor of 12,588 acres in 1765.
The house, Towlston Grange, was built while Bryan and his family were in England in 1766 or shortly after his return. On March 4, 1767, Martha and George Washington traveled to Towlston to stand as godparents for Bryan's third son, Ferdinando. The first known letter to his friend George Washington with the Towlston address is dated 1768. Washington's diaries, Bryan's letters, and Fairfax tradition recount the many happy visits that Washington made to Bryan, Elizabeth, and their young family in this home.
The Virginia census of 1782 noted Towlston Grange as having one dwelling, ten outbuildings, six white persons and 18 slaves, a modest plantation. Most of Towlston Manor was leased to farmers. In 1790, Bryan moved into a grander house he built outside of Alexandria that he named Mount Eagle. George Washington wrote Fairfax, commenting on how happy he was to have him closer to Mount Vernon."
