Ash Grove is an 18th-century plantation house in Fairfax County, Virginia, United States.
In his later years, Thomas bought Vaucluse Plantation, near Alexandria, Virginia, and bestowed Ash Grove upon his second son, Henry.
He married Caroline Herbert of Maryland, and they had several children, and operated a boarding school for young ladies.
Descendants on occasion relate some interesting family lore of American Civil War events when the neighborhood was a "no man's land.
[4] The house was purchased from the Sherman family in 1997, and dedicated as a Fairfax County, Virginia, park.
