In the winter of 1963, John and Jacqueline Kennedy bought 39 acres in Middleburg, Va., while they owned a home in Hyannis, Mass. They finished it in Oct. 1963 and dubbed it Wexford, after the Irish county where the Kennedys trace their roots. JFK was killed the following month. Three owners and 50 years later, the custom-built four-bedroom home is on sale for $10.995 million.
