Parents are first cousins.
Half-brother to Henry III of England
In 1247, a year after their mother's death, (and the French conquest of Poitou) siblings Alice, William, Aymer and Guy, accompanied the new papal legate William of Modena - the Cardinal Bishop of Sabina, to England to live at the invitation of their half-brother King Henry III. The king found important positions for all of them, to the resentment of many of the nobles who did not want the 'penniless foreigners'.
Henry dubbed him Knight on 13 Oct. 1247 in Westminster Abbey.
Became Earl of Pembroke and Wexford (titular, basically he seized his wife's assets and demanded all his neighbors respect him as such) upon his marriage to Joan Munchensi, Countess of Pembroke.
Was incredibly disliked by many, especially the barons, and especially in Wales and gained the reputation as one of the most prominent of the rapacious foreigners. Had some trouble with Simon de Montfort and participated heavily on the side of King Henry III during the Second Baron's Rebellion.
Fought at Lewes, fled to France, came back to England and fought at Gloucester and Evesham.
Accompanied Prince Edward (soon Edward I) on crusade to Palestine. Afterwards he went on to play a big part in the conquest of Wales.
Was frequently one of King Edward's representatives in public business in France (Aquitaine then being ruled by England) and was one of the King's representatives in the suit of succession to the crown of Scotland. (William's neice Isabel de Warenne being the wife of the eventual chosen King John) 1291-1292
