You are asking about Martha Washington, the wife of America's first president, George Washington. But keep in mind that the term "first lady" is fairly modern-- back in the late 1700s, it was not being used. In fact, no-one was quite sure what to call the president's wife. Martha Washington was beloved by most Americans of that time, and they called her "Lady Washington," as if she were a member of British royalty (which she was not).
