chosen.content: America's first "First Lady" Martha Washington died on May 22, 1802, at Mount Vernon, VA. After her husband and first president of the United States George Washington died in 1799, Martha assured a final privacy by burning their letters. She died of severe fever. Both George and Martha Washington are buried at Mount Vernon where the president had planned an unpretentious tomb for them.
