Graham Davenport (whose military career had begun in the Civil War) reburied George and Mary Ann Graham in the family vault at Arlington National Cemetery, where two grandsons would also be buried. Career Admitted to the Virginia bar, Graham practiced law in Dumfries (the Prince William county seat until 1803) and nearby areas, including neighboring Fairfax County. He also surveyed lands across the Appalachian Mountains in which his father had speculated, and later would speculate in land himself. In 1796, also the year of his father's death, Graham subscribed to the Quantico Creek Navigation Company, that strove to keep Dumfries as a navigable port, despite silting from Quantico Creek that in a couple of decades ended its overseas tobacco shipments. Like his father, and Mason and Brent friends, Graham owned slaves. Complicating matters, he also had a first cousin, Dr. George Graham, who operated the Graham plantation in Prince William County and had a medical practice there and in the nearest large town, Alexandria until his death in 1816. Meanwhile, this George Graham moved to the Lexington plantation in nearby Fairfax County, which his wife had selected as her share of her first husband's estate. Fairfax County voters elected Graham and fellow lawyer Thomson Mason to the House of Delegates in 1808, although neither won re-election. Graham also served as a presidential elector for Presidents Jefferson (once) and Madison (twice). During the War of 1812, Graham followed his family's tradition, volunteered to serve as captain of a cavalry company, sometimes called the Fairfax Light Horse or Dragoons. British ships anchored off Quantico Creek during the war, although local legend claimed a providential gale saved Dumfries from burning similar to that of the new national capital. Captain Graham's most important task may have occurred just months after his wife's death, when he led troops guarding gunpowder removed from the Washington Naval Yard magazine and taken to the Dulany Farm near Falls Church on September 6, 1814 (despite local consternation about the danger) before it was returned to the national capital on September 10, 1814. During that federal evacuation, Graham's former schoolmate John Mason, now a militia general, escorted President Madison, Attorney General Rush and others toward Salona, near the Little Falls of the Potomac River, to avoid British forces. The First Lady, Dolley Madison, went to Rokeby, the estate of her friend Matilda Lee Love, about a mile away, while various
