Capon Chapel's cemetery is surrounded by a wrought iron fence made by Stewart Iron Works, and contains the remains of John Monroe, William C. Nixon, West Virginia House of Delegates member Captain David Pugh (1806–1899), American Civil War veterans from the Union and the Confederacy, and free and enslaved African Americans. Capon Chapel, along with its cemetery, was added to the National Register of Historic Places on December 12, 2012, in recognition of its representation of the rural religious architecture of the Potomac Highlands region, and for its service as an important rural church in Hampshire County.
