Yves DE CREIL , Sieur d'Alençon et de Bellême

  General Notes:

https://en.wikipedia.org/wiki/Yves_de_Creil
His parentage is unknown but by his name he was associated with Creil, a small town in the territory belonging to Bernard, Count of Senlis. It is known that he served king Louis IV d'Outremer about 945 in the somewhat ambiguous capacity of a royal balistarius (Latin meaning variously crossbowman, operator of a siege engine, or as one in charge of siege equipment).

In 942 his actions helped save the life of Richard, Duke of Normandy, who was effectively held a prisoner by King Louis IV of France at Laon. The king was planning to kill or mutilate the young Richard so as to take control of Normandy himself. Yves de Creil learned of the plot and passed the information to the boy's tutor, Osmund, who then took Richard secretly to the safety of the castle of Coucy, held by Bernard of Senlis.

While the French writers, including Prentout, accepted that Yves de Criel was the father of Yves de Bellême, Geoffrey H. White was of the opinion that, while probable, it should not be stated as fact.

Geoffrey H. White was certain that Yves de Creil and Yves de Bellême, though often confused, were not one and the same person. While the French writers accepted that Yves de Creil was the father of Yves de Bellême, there remains some question they were even of the same family. See White, 'The First House of Bellême', TRHS, 22, pp. 69-70. Alternatively see: Henri Prentout, Études sur quelques points d'histoire de Normandie(Impr. Lanier, Caen, 1926, p. 89.

Yves married Hildeburge DE BEAUMONT-AU-MAINE , Dame de Beaumont-au-Maine. (Hildeburge DE BEAUMONT-AU-MAINE , Dame de Beaumont-au-Maine was born about 930 in Ponthieu, Ain, Rhone-Alpes, France and died in 1004 in Normandie, France.)
