• Background Information. 141
Ascelin Goel, son and heir. He took part in William the Conqueror's invasion of the French Vexin in July 1087 and destroyed the vineyards round Mantes. He built a strongly fortified castle at Breval. In 1089 he took the castle of Ivry by stratagem from William de Bréteuil and delivered it up to Duke Robert. William redeemed the castle from the Duke and deprived Ascelin of the provostship of Ivry. Thereafter Ascelin captured William, and rigorously imprisoned him at Breval until he obtained his freedom on the terms of a money payment, the cession of the castle of Ivry and the marriage of his daughter Isabel to Ascelin. In the following year, William attempted to retake the castle, but was defeated by Ascelin, the abbey of Ivry being burnt in the conflict. William then, appealed to the King of France and the Duke of Normandy, who in, the spring of 1092, aided by a levée en masse of the surrounding population, besieged Ascelin at Breval. Ascelin was forced to capitulate and surrender the castle of Ivry, which was restored to William. On the death of William de Bréteuil in 1103, Ascelin took the part of William's nephew, Ralf de Grancei, against Eustace de Bréteuil, William's illegitimate son, in the struggle for the succession.

He married Isabel, illegitimate daughter of William de Bréteuil, son and heir [in Normandy] of William Fitz Osbern, 1st Earl of Hereford. He died between 1116 and 1119.
