The Heritage Farmstead Museum (HFM) is the premiere living history site interpreting the Texas black-land prairie region in north-Texas. Also known as the Ammie Wilson House it is a historic farm museum in Plano, Texas.
The late-Victorian farm-house was built in 1891 on a 365 acre farm belonging to Mary Alice Farrell and her husband Hunter Farrell, a landowner and businessman whose family had moved to Texas from Virginia. The Farrells divorced in 1929 and eventually their daughter Ammie took over management of the farm and became a award winning livestock breeder before her death in 1972. The farm was added to the National Register of Historic Places in 1978. In 1986 the farm opened as a living museum utilizing the remaining 4.5 acres surrounding the home. The museum is accredited by the American Alliance of Museums. The one room school house is a reconstruction.
