Fairfax County no relation Virginia George Washington
Mount Vernon is an American landmark and former plantation of Founding Father, commander of the Continental Army in the Revolutionary War, and the first president of the United States George Washington and his wife, Martha. The estate is on the banks of the Potomac River in Fairfax County, Virginia. It is located south of Washington, D.C., and Alexandria, Virginia, and is across the river from Prince George's County, Maryland. 
The Washington family acquired land in the area in 1674. Around 1734, the family embarked on an expansion of its estate that continued under George Washington, who began leasing the estate in 1754 before becoming its sole owner in 1761.The mansion was built of wood in a loose Palladian style; the original house was built by George Washington's father Augustine, around 1734. George Washington expanded the house twice, once in the late 1750s and again in the 1770s. It remained Washington's home for the rest of his life. Following his death in 1799, under the ownership of several successive generations of the family, the estate progressively declined as revenues were insufficient to maintain it adequately. 
In 1858, the house's historical importance was recognized and it was taken over by the Mount Vernon Ladies' Association; this organization acquired it together with part of the Washington property estate. The mansion and its surrounding buildings did escape damage from the American Civil War suffered by many properties located within the Confederate States of America.
Mount Vernon was designated a National Historic Landmark in 1960 and is listed on the National Register of Historic Places. It is still owned and maintained in trust by the Mount Vernon Ladies' Association, being daily open to the public. Allowing people to see the estate is part of an over 200-year-old tradition started by George Washington. In 1794 he wrote: "I have no objection to any sober or orderly person's gratifying their curiosity in viewing the buildings, Gardens, &ca. about Mount Vernon."Name
When George Washington's ancestors acquired the estate, it was known as Little Hunting Creek Plantation, after the nearby Little Hunting Creek. However, when Washington's older half-brother, Lawrence Washington, inherited it, he renamed it after Vice Admiral Edward Vernon,  who had been his commanding officer during the War of Jenkins' Ear and captured Portobelo from the Spanish. When George Washington inherited the property, he retained the name.George Washington
Lawrence died in 1752, and his will stipulated that his widow should own a life estate in Mount Vernon, the remainder interest falling to his half-brother George; George Washington was already living at Mount Vernon and probably managing the plantation. Lawrence's widow, Anne Fairfax, remarried into the Lee family and moved out. Following the death of Anne and Lawrence's only surviving child in 1754, George, as executor of his brother's estate leased his sister-in-law's estate. Upon the death of Anne Fairfax in 1761, he succeeded to the remainder interest and became sole owner of the property.In 1758, Washington began the first of two major additions and improvements by raising the house to two-and-a-half stories. The second expansion was begun during the 1770s, shortly before the outbreak of the Revolutionary War. Washington had rooms added to the north and south ends, unifying the whole with the addition of the cupola and two-story piazza overlooking the Potomac River. The final expansion increased the mansion to 21 rooms and an area of 11,028 square feet. The great majority of the work was performed by enslaved African Americans and artisans.Preservation, legacy and tourism
Following Martha Washington's death in 1802, George Washington's will was carried out in accordance with the terms of his bequests. The largest part of his estate, which included both his papers and Mount Vernon, passed to his nephew, Bushrod Washington, an Associate Justice of the Supreme Court of the United States. The younger Washington and his wife then moved to Mount Vernon.Bushrod Washington did not inherit much cash and was unable to support the upkeep of the estate's mansion on the proceeds from the property and his Supreme Court salary. He sold some of his own slaves to gain working capital. However, the farms' low revenues left him short, and he was unable to adequately maintain the mansion.
