The community of Newington derives its name from the second glebe house of Truro Parish, completed in 1760 and so named after becoming the private residence of Richard and Sarah McCarty Chichester sometime after 1767. The house itself was purchased by the family of William Nevitt, in 1828, along with 1000 acres of land; they occupied the building until it burned in 1875. The Alexandria and Fredericksburg Railroad opened a railway station on the property in April 1872. Originally known as the Long Branch Station and later renamed Accotink and then Newington, it was closed in 1971; it is remembered by a historic marker erected by the Fairfax County History Commission in 2005. Also in the Newington area are the remains of the Mount Air plantation, originally granted to Dennis McCarty in 1727. The house was destroyed by fire in 1992, but ruins remain; they, too, are denoted by a historic marker, erected in 2006, and are owned by the Fairfax County Park Authority, which interprets the site.
