House of Normandy

The House of Normandy (Norman: Maison de Nouormandie [mɛ.zɔ̃ d̪e nɔʁ.mɛnde]) designates the noble family which originates from the Duchy of Normandy and whose members were dukes of Normandy, counts of Rouen, as well as kings of England following the Norman conquest of England. It lasted until Stephen of the French House of Blois seized the English throne and the Duchy of Normandy in 1135. The house emerged from the union between the Viking Rollo (first ruler of Normandy) and Poppa of Bayeux, a West Frankish noblewoman. William the Conqueror and his heirs down through 1135 were members of this dynasty while nearly every English monarch since William have been his descendant.

After that it was disputed between William's grandchildren, Matilda, whose husband Geoffrey was the founder of the House of Plantagenet, and Stephen of the House of Blois (or Blesevin dynasty).
