House of Normandy
The House of Normandy is the usual designation for the family that were the counts of Rouen, dukes of Normandy and kings of England which immediately followed the Norman conquest of England and lasted until the House of Plantagenet came to power in 1154. The house emerged from the union between the Viking Rollo (first ruler of the Duchy of Normandy) and Poppa of Bayeux, a West Frankish noblewoman. William the Conqueror and his heirs down through 1135 were members of this dynasty.
