About Guillaume de Poitou (Plantagenet), Comte de Poitou

http://en.wikipedia.org/wiki/William_X_of_Poitou

William (22 July 1136 at Argentan, Normandy, - 30 January 1163/64 at Rouen, Normandy) was the youngest of the three sons of Geoffrey Plantagenet, Count of Anjou and Empress Matilda, daughter of King Henry I of England. His eldest brother was King Henry II of England, and his 2nd brother was Geoffrey, Count of Nantes. William was Viscount of Dieppe and Count of Poitou. He was also known as William FitzEmpress and as William of Anjou.

In 1156 he was with his brother Henry at the siege of Chinon. This siege was occasioned by the rebellion of their brother Geoffrey He also conducted the siege at the castle of Mountreuil-Bellay. While doing so he had the writings of the Roman military theorist Vegetius read to him; he then did what Vegetius had done, and the siege ended the next day.

In September, 1155, King Henry held a council at Wincester where he enthusiastically considered invading Ireland and giving it to William, making him king. The plans were abandoned when their mother Empress Matilda objected, as she did not consider Ireland worth conquering. Henry did, however, make William one of the richest men in England, granting him seven manors (Maldon in Essex; Dartford, Hoo, and Shorne in Kent; Aylsham and Cawston in Norfolk; and Hintlesham in Suffolk). He also had land surrounding Dieppe, Normandy, of which he was made vicomte (viscount).

In 1162 his marriage to Isabel de Warenne, 4th Countess of Surrey, was arranged. She was one of the great heiresses in England, being the widow of William of Blois, count of Boulogne and Mortain, the son of King Stephen of England, and a cousin of William. Because of this relationship a dispensation from affinity was required for the marriage to take place; such dispensations were usually granted without difficulty. Thomas Becket, archbishop of Canterbury refused to support the request for a dispensation and it was not granted because of that. William died suddenly shortly after that, it was said of a broken heart. He was buried in the Cathedral of Notre-Dame in Rouen. Henry blamed Thomas Becket for his brother's death, and this might well be the beginning of the great conflict between them. When Becket was murdered 29 December 1170, one of the knights who killed him was Richard le Breton who had been in William's employ. When he delivered his fatal blow he shouted "take that, for the love of my lord William, the king's brother!"
