George Augustine Washington (c.1758–1793) was the oldest son of GW’s brother Charles. He served as a major in the Continental army and as Lafayette’s aide during the Revolution. In 1785 he married Frances Bassett (1767-1796), the daughter of Martha Washington’s sister and brother-in-law, Anna Marie Dandridge Bassett and Col. Burwell Bassett of Eltham in New Kent County, Virginia. The young couple made their home with the Washingtons, and when GW departed for New York in April 1789, George Augustine was left in charge of Mount Vernon.
