First Evidence of Human Activity at Mount Vernon
The first evidence of human occupation in the area that is now Mount Vernon occurred during the Archaic period, sometime between 10,000 and 4,500 years ago. At that time, the Chesapeake Bay was formed, which created a diverse environment for plant and animal species. Mount Vernon was a part of the ancestral homelands of the Doeg people, who had a settlement at Mason Neck (long called “Doeg Neck”). The land was also situated across the river from a major Piscataway settlement in what is today Piscataway Park, a site which also housed a Susquehannock fort in the late seventeenth century.
Early Years
Much of the land that would become George Washington's Mount Vernon Estate was held in the Washington family since 1674 when Lord Thomas Culpeper, proprietor of the Northern Neck of Virginia, granted 5,000 acres of land on the Potomac to Colonel Nicholas Spencer and Lieutenant Colonel John Washington. Culpeper's 1674 grant consisted of a peninsula in the Potomac River, bordered by Dogue Run and Little Hunting Creek. The land was divided between Washington and Spencer, but the entirety of the grant would one day become George Washington's Mount Vernon. At that time, John Washington was not using this tract at their primary residence, instead living in Westmoreland County, Virginia.
His son Lawrence Washington inherited the land in 1677, upon the death of his father. In 1690, the original land granted by Lord Culpeper was divided equally between the Washington and Spencer families. Lawrence received the eastern half of the land bordered by Little Hunting Creek, known as the Little Hunting Creek Plantation. The Spencers family received the western part of the neck, lying along Dogue Run.
From Lawrence, the plantation passed to his young daughter Mildred in 1698. In 1726, Mildred and her husband Roger Gregory sold the estate to her brother, Augustine Washington for £180 sterling.
Augustine Washington
Around 1734, Augustine brought his second wife, Mary Ball Washington, and their young family—including the two-year-old George Washington—to Little Hunting Creek where they lived for a few years. During this time, dendrochronology, or the use of tree ring analysis to determine relative dating, shows the trees used to frame this section of the house were cut in 1734. The original house likely consisted of four rooms and a central passage on the first floor and a garret.
Lawrence Washington
Augustine deeded the plantation to his eldest son from his first marriage Lawrence Washington and on his death in 1743 the gift was confirmed in his will. Not long after, Lawrence Washington settled at the plantation and renamed "Mount Vernon," in honor of his former commander Admiral Edward Vernon. Lawrence made the first additions to the original Washington holdings when he purchased around 170 acres on Dogue Run; this land eventually became the site of the Washington grist mill. Lawrence remained the proprietor of Mount Vernon until his death in 1752.
Lawrence Washington bequeathed a life interest in Mount Vernon to his widow Ann Fairfax Washington, with the provision that the estate should afterward pass to Sarah, the couple's only living child. But should their daughter die without issue, Mount Vernon was to become the property of Lawrence's half-brother, George Washington. Sarah died even before her father's will was probated. Ann Fairfax Washington soon became Mrs. George Lee, putting an end to any plans she may have had of remaining at Mount Vernon.
George Washington
George Washington took advantage of the opportunity to take over the plantation. On December 17, 1754, Washington leased Ann's life interest in Mount Vernon for yearly rent specified as his choice of 15,000 pounds of tobacco or £100 cash. Colonel Washington was just twenty-two years old. In 1757, Washington paid his neighbor Sampson Darrell £350 for 500 acres along Mount Vernon's northern boundary. In 1760, he made his largest single addition when he purchased a sizeable tract on the opposite bank of Little Hunting Creek from William Clifton. When Anne Fairfax Washington Lee died in 1761, George Washington became the owner of the plantation.
Washington snapped up a series of small adjoining parcels near the headwaters of Dogue Creek. In 1761 he paid John Ashford £150 for 135 acres. The following year he bought another 135 acres from Ashford's brother George. Around the same time, he added 178 acres from Simon Pearson to Dogue Run. This tract was the only land at Mount Vernon that George Washington would ever part with, deeding 460 acres to Lund Washington in 1785. Dogue Run grew by another 200 acres when Washington bought a tract from William and Diane Whiting in 1764. It was here that he would build the pond and mill race to power his grist mill.
George Washington bought no more land for the next five years due to financial concerns. Confident that he had escaped calamity, he was emboldened to turn again to the task of gathering new lands. Washington's first acquisition of 1769 was 100 acres bought from George Mason. He soon had his eyes on a richer prize—the 200 riverfront acres of his old friend and neighbor, Captain John Posey. In October of 1769, most of Posey's property was sold in a court-ordered auction. At this sale, Washington acquired 200 acres of Potomac farmland.
In 1770 Washington purchased a parcel from John West north of the land he had previously acquired from Posey. In the same year, he added 75 acres from Valinda Wade to Dogue Run Farm. Washington's old pastime of surveying along the borders of his estate paid off in 1771 when he stumbled on a small plot of twenty acres adjoining Dogue Run that had never been claimed from the Northern Neck Proprietary. He applied directly to the Proprietor, his old patron Lord Fairfax, and soon received a patent for the land. Washington made his last purchase before the Revolution when he paid Charles West twenty-five shillings an acre for 412 acres on the western side of Dogue Run. A generation later this tract would become the Woodlawn home of Eleanor Parke Custis Lewis and her husband, Washington's nephew, Lawrence Lewis.
George Washington: Expansion During and After the Revolutionary War
On May 4, 1775, Washington rode away from Mount Vernon on his way to the Continental Congress in Philadelphia. About six weeks later, Congress appointed him to lead the Continental Army. Yet even the burdens of military command did not deter him from his quest to buy up the last lands remaining from the old Spencer-Washington patent. In 1779, Washington struck a deal with Thomas Marshall for another 480 acres, and in June of 1783 Washington bought 118 acres from William Barry.
After the war, Washington turned his attention to the approximately 650 acres left to complete the estate. Most of this land was owned by the widow Penelope French and managed by her son-in-law, Benjamin Dulaney. Sandwiched in the middle of Mrs. French's land was a tract controlled by William Triplett. By the end of 1786, Washington bought Triplett's land, and also arranged a trade with Dulaney. Washington finally owned all of the land between Dogue Run and Little Hunting Creek.
Washington added more than 5,000 acres to his estate, starting with his first purchase in 1757. Although he described Mount Vernon as around 8,000 acres, the true figure was closer to 7,600 or almost exactly twelve square miles. The four working farms—River, Dogue Run, Union, and Muddy Hole—contained around 3,300 acres of cultivated ground while the rest remained in woodlands. Mansion House Farm encompassed another 500 acres including Washington's home, his gardens, lawns, and vistas.
After Washington’s Death
Washington did not have biological children. His nephew Bushrod Washington (1762-1829), the son of his brother, John Augustine Washington (1736-1787) and Hannah Bushrod Washington (1736-1801) inherited most of Mount Vernon after the death of Martha Washington in 1802. The tract once a part of Dogue Run Farm was inherited by Eleanor Parke Custis Lewis and her husband Lawrence Lewis. While those enslaved by Washington were manumitted, those enslaved by Martha were inherited by her children and trafficked away from Mount Vernon. Upon moving to Mount Vernon, Bushrod also brought an enslaved labor force, including many families from Bushfield in Westmoreland County whom he had inherited from his parents after their deaths. As agricultural prospects declined with worsening soil and little time to manage farmland, Bushrod began to sell off some outlying lands. Visitors often made pilgrimages to Washington’s tomb, trampling the grounds.
Bushrod and his wife Ann Blackburn Washington (1768-1829) did not have any children, but assisted in raising various nieces and nephews at Mount Vernon. Bushrod willed the property to his nephew John Augustine Washington (1792-1832) after his death in 1829. Shortly after inheriting Mount Vernon, John Augustine died. His son John Augustine Washington III (1821-1861), the great-grandnephew of George Washington, became the last Washington family owner of Mount Vernon. He lived there with his wife Eleanor Love Seldon (1824-1860), and their six children. He made some modifications to the interior of the mansion including changes to south door frame. He sold it to the Mount Vernon Ladies Association in 1858, who began preserving Mount Vernon to reflect its appearance during George Washington’s life time for future generations.
