The plantation that became Exeter was inherited by Mary Mason Seldon; a sister of Thomson Mason, from their mother Ann Thompson Mason. This Mary Mason Seldon married, first, Mann Page and upon his death took as her second husband her first cousin Dr. Wilson Cary Seldon who, born in 1761, had served as surgeon in a Virginia artillery regiment during the Revolution. Though she had children by Page and none by Seldon, the latter secured this land and between 1796 and 1800 built the main frame dwelling with its pleasing design and interesting detail. The large brick extension in the rear was added by General George Rust about 1854 during his ownership of the estate. By his second wife, Dr. Seldon had a daughter, Eleanor, and it was at Exeter on the 16th February 1843, that she married John Augustine Washington, the last of his family to own and occupy Mount Vernon. When the War Between the States broke out, he at once volunteered for service, became an aide on the staff of General Lee with the rank of lieutenant colonel and was killed in a small engagement, which otherwise would have been unimportant, at Cheat Mountain, now West Virginia, on the 13th September, 1861. In 1857 Exeter was purchased by the late Horatio Trundle. It was inherited by his son Mr. Hartley H. Trundle who with his family resides there. SELMA Selma, another part of Mrs. Ann Thomson Mason's great purchase of "wild lands," saw its first mansion built between 1800 and 1810 by General Armistead Thomson Mason, United States Senator from Virginia (affectionately known as "the Chief of Selma") when he was killed by his cousin, John Mason McCarty, in the famous duel at Bladensburg on the 6th February, 1819. He had inherited the land from his father Stevens Thomson Mason of Raspberry Plain. The property was purchased in 1896 by the late Colonel Elijah B. White, who afterward represented the Loudoun district in the Virginia Senate and was for many years a prominent Leesburg banker. He was a son of the much-loved leader of White's Battalion in the War of 1861. Upon his purchase of the estate, Colonel White built the present stately mansion, so famed for its hospitality, in which he incorporated parts of the older house, burned some years before. Selma is now owned by Colonel White's widow (who before her marriage was Miss Lalla Harrison) and his daughter, Miss Elizabeth White. It long has had the reputation of being one of the most fertile and successfully managed farming estates in the East. ALDIE MANOR Aldie Manor, in the present town of Aldie, was built by Charles Fenton Mercer and named for Aldie Castle in Scotland, the home of the Mercer family. The town in turn was named for the estate and the Magisterial District in which both lie is named for Mercer. The mansion has long been owned and occupied by the diZerega family. MORVEN PARK
