Also called Geoffrey Plantagenet, by name Geoffrey The Fair, French Geoffroi Plantagenet, or Geoffroi Le Belcount of Anjou (1131-51), Maine, and Touraine and ancestor of the Plantagenet kings of England through his marriage, in June 1128, to Matilda (q.v.), daughter of Henry I of England.
On Henry's death (1135), Geoffrey claimed the duchy of Normandy; he finally conquered it in 1144 and ruled there as duke until he gave it to his son Henry (later King Henry II of England) in 1150.
Geoffrey was popular with the Normans, but he had to suppress a rebellion of malcontent Angevin nobles. After a short war with Louis VII of France, Geoffrey signed a treaty (August 1151) by which he surrendered the whole of Norman Vexin (the border area between Normandy and Île-de-France) to Louis.
Goeffrey V Plantagent, Duke of Normandy, Count of Anjou usually wore on his helmet a sprig of the broom and the French words for this (plante and genet) became the English name Plantagenet.
Geoffrey married Adelaide Matilda (Maud) FitzRoy Duchess Of Bretagne, daughter of King Henry I "Beauclerc" of England and Edith Matilda "Atheling" Princess Of Scotland, on 22 May 1128 in Lemans, Anjou, Maine, France. (Adelaide Matilda (Maud) FitzRoy Duchess Of Bretagne was born on 5 Aug 1102 in London, Middlesex, England, died on 10 Sep 1167 in Notre Dame, Rouen, Seine-Maritime, France and was buried in Sep 1167 in le Bec-Hellouin, Eure, France.)
Geoffrey next married Mrs. Geoffrey V. (Mrs. Geoffrey V was born about 1112 in Normandy, France.)
