- Ashburn was originally called Farmwell (variant names include Old Farmwell and Farmwell Station) after a nearby mansion of that name owned by George Lee III. The name "Farmwell" first appeared in George Lee's October 1802 will and was used to describe the 1,236 acre (5.0 km²) plantation he inherited from his father, Thomas Ludwell Lee II. A section of Farmwell plantation west of Ashburn Road, a 580 acre (2.3 km²) tract, was purchased in 1841 as a summer home by John Janney, a Quaker lawyer who nearly became Vice President of the United States. Janney called the property Ashburn Farm; the name's first known appearance in writing is 1870, when he sold the property. It is likely he named the farm after family friends whose name was "Ashburn".
