 The deaths within three years of the Dauphin, two of his three sons, his daughter-in-law and the little Duke of Brittany led to widespread rumours that Orléans had poisoned them all to gain the throne.In fact, the Dauphin died of smallpox, the Duc de Berry in a riding accident and the others of measles, but they did great damage to Orléans' reputation, and even Louis XIV seems to have at least half-believed them.Only in Orléans' last years did the obvious affection between himself and Louis XV, and the young King's robust health, cause the rumours to die away.
