George Mason V

George Mason V of Lexington (30 April 1753 – 5 December 1796) was a planter, businessman, and militia leader. Mason was the eldest son of United States patriot, statesman, and delegate from Virginia to the U.S. Constitutional Convention, George Mason IV and his wife Ann Eilbeck. He received his early education from private tutors at Gunston Hall and was given Lexington plantation on Mason's Neck by his father in 1774. In 1775, he named his plantation to commemorate the Battle of Lexington in Massachusetts.

Mason joined the Fairfax County Independent Militia in 1775 and was elected Ensign. He developed a rheumatic disorder that plagued him for the remainder of his life. In 1776, he commanded a militia company sent to Hampton, Virginia to protect the coast from Lord Dunmore's assaults, but was forced to quit the military on account of his increasingly poor health. He travelled to France between 1779 and 1783 for business purposes and to improve his health. At his father's request, George Washington wrote Mason letters of introduction to the marquis de Lafayette and Benjamin Franklin in Paris. While in France, he settled in Nantes, where he became involved in the tobacco trade and occasionally arranged for shipments of goods to his father.

Upon the death of his father in 1792, Mason inherited the entirety of Mason's Neck. He died four years later at Lexington, on 5 December 1796, after suffering from chronic ill health for his entire adult life. He was interred in the Mason family graveyard at Gunston Hall. In 1803, his widow Betsey married George Graham.

His will divided Mason's Neck into two approximately equal tracts along a north-south axis from Causeway Point to Martin Cockburn's south boundary line. His eldest son George Mason VI received the eastern tract with the ownership privilege of either Lexington or Gunston Hall, of which he chose the latter. Another of his sons, William Eilbeck Mason, received the western half of the Neck.
