In November 1677, Anne's elder sister, Mary, married their Dutch first cousin, William III of Orange, at St James's Palace, but Anne could not attend the wedding because she was confined to her room with smallpox. By the time she recovered, Mary had already left for her new life in the Netherlands. Lady Frances Villiers contracted the disease, and died. Anne's aunt Lady Henrietta Hyde (the wife of Laurence Hyde) was appointed as her new governess. A year later, Anne and her stepmother visited Mary in Holland for two weeks.
