HOSLEY FAMILY CEMETERY
Behind the Washington Farm United Methodist Church at 3921 Old Mill Road
South Alexandria, Virginia USA
Original Information from Volume 5 of the Gravestone Books
The Hosley Family Cemetery is located about twenty feet behind the Washington Farm United Methodist Church at 3921 Old Mill Road. The church was formerly the McLaughlin Farm United Methodist Church and the cemetery has also been known as “Unnamed Cemetery - Old Mill Road.”
When H. B. and Carrie Hosley sold their property to Wesleyan Pentecostal Church on 16 December 1923 (Deed Book F9, page 543), they reserved a plot measuring 20 feet (north to south) by 50 feet (east to west) as a family burial ground.
The cemetery is surrounded by a low chain fence. There are four holly trees standing near a single granite monument. The cemetery is well integrated into the churchyard and is very well maintained. It was surveyed in 1994 and 1998.
