1802: The first of first ladies, Martha Dandridge Custis Washington, died of a severe fever. When she married George Washington in January 1759, she was 27 years old and a widowed mother of two. She was also one of the wealthiest women in Virginia, having inherited some 15,000 acres of farmland from her deceased husband, Daniel Parke Custis. A prosperous farmer himself, George Washington ably took over the Custis estate, but moved Martha and his newly-adopted stepchildren Martha ("Patsy") and John Parke ("Jacky") to his own home, Mount Vernon, outside Alexandria, Virginia. There, the couple delighted in raising their children (though Patsy died of an epileptic seizure in 1773 at the age of 17, while Jacky died of camp fever during the Revolution in 1781) and entertaining Virginia society. It is estimated that between 1768 and 1775 over 2,000 guests visited Mount Vernon, some staying for extended periods. (Source: Library of Congress)
