William Grayson (b.1736) was one of Prince William County’s most distinguished politicians and soldiers during the Revolutionary War era. Grayson was extremely active in local politics in the years leading up to the Revolution, signing both the Leedstown Resolutions and Prince William County Resolves in response to the Stamp and Intolerable Acts, respectively. At the outbreak of hostilities, he was made commander of the Prince William Battalion, and in 1776, joined the Continental service as a secretary and later aide-de-camp to General George Washington. The following year, he was made colonel of Grayson’s Additional Continental Regiment and fought at the battles of Brandywine, Germantown, and Monmouth. In 1779, he was appointed to the Board of War and returned home in 1781. After the war, he became one of Virginia’s first senators and died on March 12, 1790. He was laid to rest in the family tomb at Belle Air.
