George Washington

Context: George Washington was the first child of Augustine Washington and his second wife Mary Ball Washington, born on their Popes Creek Estate near Colonial Beach in Westmoreland County, Virginia. He was born on February 11, 1731, according to the Julian calendar and Annunciation Style of enumerating years then in use in the British Empire. The Gregorian calendar was adopted within the British Empire in 1752, and it renders a birth date of February 22, 1732.  Washington was of primarily English gentry descent, especially from Sulgrave, England. His great-grandfather John Washington immigrated to Virginia in 1656 and began accumulating land and slaves, as did his son Lawrence and his grandson, George's father Augustine. Augustine was a tobacco planter who also tried his hand at iron manufacturing, and later he was the Justice of the Westmoreland County Court. In Washington's youth, his family was moderately prosperous and considered members of Virginia's "country level gentry" of "middling rank," rather than one of the leading wealthy planter elite families. His wife Sally was also a friend of Washington and an early romantic interest, and maintained correspondence when she moved to England with her father, but most of the letters were intercepted by the British during the war.  Lawrence Washington inherited a plantation from their father on the Potomac River at Little Hunting Creek which he named Mount Vernon in honor of his commanding officer Vice Admiral Edward Vernon. Washington inherited Ferry Farm upon his father's death and eventually acquired Mount Vernon after Lawrence's death.  The death of his father prevented Washington from an education at England's Appleby Grammar School such as his older brothers had received. He achieved the equivalent of an elementary school education from a variety of tutors, as well as from a school run by an Anglican clergyman in or near Fredericksburg. His education totaled seven or eight years, while he lived with relatives at various places that included the Westmoreland and the Chotank regions of Virginia, as well as Ferry Farm and Mount Vernon. He was trained in mathematics, trigonometry, and surveying that developed a natural talent of draftsmanship and map making. He was also an avid reader and purchased books on military affairs, agriculture, and history, as well as the popular novels of his times. There was talk of securing an appointment for him in the Royal Navy when he was 15, but it was dropped when his widowed mother objected.  In 1751, Washington traveled with Lawrence to Barbados (his only trip abroad) in the hope that the climate would be beneficial to Lawrence's declining health, as he was suffering from tuberculosis. Washington contracted smallpox during the trip, which left his face slightly scarred but immunized him against future exposures to the disease. Lawrence's health failed to improve, and he returned to Mount Vernon where he died in the summer of 1752. His position as Adjutant General (militia leader) of Virginia was divided into four district offices after his death, and Washington was appointed by Governor Dinwiddie as one of the four district adjutants in February 1753, with the rank of major in the Virginia militia. He also became a freemason while in Fredericksburg during this period, although his involvement was minimal. CANNOTANSWER
