Cedar Lawn, also known as Berry Hill and Poplar Hill, is one of several houses built near Charles Town, West Virginia for members of the Washington family. Cedar Lawn was built in 1825 for John Thornton Augustine Washington, George Washington's grand-nephew. The property was originally part of the Harewood estate belonging to Samuel Washington. The property that eventually became Cedar Lawn was left to Samuel's son, Thornton Washington, who built "Berry Hill", named for his wife's family. Berry Hill was destroyed by fire, and John Thornton Augustine built Cedar Lawn when he inherited.
