[Illustration: THE FRONT PORCH AT ROCKLAND, Home of the Rusts. Built in 1822 by General George Rust and still owned by his family.] MORRISWORTH The 750 acres which originally composed Morrisworth were given by William Ellzey to his daughter Catherine who married Mathew Harrison of Dumfries. After his death his widow, with her children, took possession of her patrimony and in 1811 built thereon the main part of the stone mansion. There she resided for the remainder of her life and reared her large family. Her children continued to own the estate until they sold it about 1870 to their kinsman Dr. Thomas Miller of Washington who, dying about two years later, never resided there. He left the property to his daughters, the mansion and about 550 acres going to Miss Virginia Miller and Mrs. Arthur Fendall. In turn these ladies deeded the estate in 1900 to Mrs. Fendall's son Thomas M. Fendall, the present owner, who, in 1915, added the south wing to the house. Mr. and Mrs. Fendall have greatly enlarged and developed the gardens, specializing in iris to such an extent that Morrisworth has become widely known not only for the beautiful scene when the five thousand plants are in bloom but for the many new varieties of iris originated there. CHESTNUT HILL Chestnut Hill near the Point of Rocks, so long identified with the Mason Family, is another of the mansions built about 1800. Samuel Clapham, the son of the second Josias Clapham, was the builder on land he had acquired in 1796 from his father. It came to Thomas F. Mason through his marriage to Betsey Price, a granddaughter of the second Josias as related in Chapter VII. It is now owned and occupied by Mr. and Mrs. Coleman Gore. ROCKLAND Rockland, four miles north of Leesburg, was built by General George Rust in 1822 on land acquired by him in 1817 from the heirs of Colonel Burgess Ball and is unique among the county's old estates in that today it still is owned by a descendant of its builder, Mrs. Stanley M. Brown, who before her marriage was Miss Elizabeth Fitzhugh Rust, the only child of the late owner, Mr. Henry B. Rust. Mr. and Mrs. Brown, with their children, spend each summer at Rockland. The 419 acres of the present estate border for a long distance on the Potomac and are regarded as equalling in fertility any land in the county. During the War Between the States the old house witnessed the alternate passing and repassing of the armies of the North and South in front of it along the old Carolina Road. Hospitality and gracious living have long been synonymous in Loudoun with the very name of Rockland. [Illustration: GENERAL GEORGE RUST (1788-1857). The builder of Rockland.] EXETER
