From Tardis Wiki, the free Doctor Who reference

William of Orange was an English king who died on 8 March 1702 — at least according to a newspaper that the Fifth Doctor and Turlough read. His death caused ordinary English subjects to toast the health of the heir-apparent, Princess Anne. He was the William referred to in the phrase "William and Mary". (AUDIO: Phantasmagoria)
