- William IV of Ponthieu
William III Talvas (1179 –
October 4 ,1221 ) was William III, Count ofPonthieu and William IV (of the house of Belleme/Montgomery). He was Count ofPonthieu , ruler of a small province in northern France that fell under the suzerainty of the dukes of Normandy (later also kings of England) since at least the mid 11th century. He was son and heir ofJohn I, Count of Ponthieu (d 1191) by his third wife Beatrice de St Pol.Family history and background
His father Jean I, Count of Ponthieu (d 1191 was the son of
Guy II, Count of Ponthieu (who died on the Second Crusade 1147) and grandson ofWilliam III of Ponthieu , also frequently called William III Talvas, and who represented the senior line of the lords of Montgomery, once trusted vassals and allies ofWilliam the Conqueror .Marriage to Alys, Countess of the Vexin
Talvas was married on
August 20 ,1195 toAlys, Countess of the Vexin , the daughter of KingLouis VII of France . She was some eighteen years older than he, and had previously been seduced by KingHenry II of England while betrothed to his son, King Richard the Lion-Hearted. Richard sent her back to her brother, KingPhilip II of France , refusing to marry his father's mistress.Philip then arranged for Alys to marry William Talvas, with the intent that the couple would be childless, and he would thus gain control of Ponthieu, a small but strategically important county. However, Alys then gave birth to a daughter and heiress, Marie, in 1197/1198. This daughter was the maternal grandmother of
Eleanor of Castile , first wife of Edward I, King of England, to whom Ponthieu and the disputed Vexin inheritance would eventually pass as Eleanor's dowry. William Talvis died in 1221, his daughter Marie being his heiress.ources
