Rollo was the great-great-great-grandfather of William the Conqueror, the progenitor of House of Normandy in England; however, Charles III and the British Royal Family are not direct male-line descendants of Rollo, as the House of Normandy ended with the death of Henry I. However, the House of Plantagenet was influenced by the Norman dynasty, as Empress Matilda, the mother of Henry II of England was the daughter of the Norman king Henry I.
