This was the home of Antonia Ford, imprisoned as a spy following Ranger Mosby's night capture of the local Union commander, Brig. Gen. Edwin H. Stoughton, March 9, 1863. A search of the house had revealed an honorary aide-de-camp commission to Antonia from Gen. Jeb Stuart. Union Maj. Willard, a former Provost Marshal at Fairfax Court House, fell in love with Antonia, secured her release and married her. Currently an office building.
