The name Dunwoody developed from a spelling error. Soon after the Civil War ended, Maj. Charles Dunwody left nearby Roswell to settle in a new community and decided to start a post office. The post office added one "o" to his name, and from that moment, the area was known as Dunwoody. Beginning as a humble farming community, Dunwoody grew into a popular suburb of Atlanta. Careful growth control, under the supervision of the Dunwoody Homeowners Association, kept Dunwoody from becoming too developed. The Dunwoody Preservation Trust works to identify and save Dunwoody's historical landmarks. The Dunwoody Farmhouse, located at the central crossroads of the community, is one of the trust's success stories and is enjoyed by many.
