Note 6 — Chapter X

Historians have not mentioned an uterine sister of William, called Muriel. We remarked, at p. 45, their error as to Adelidis, usually so reckoned; but who, as we have seen, was of the whole blood, and married Enguerran, count of Ponthieu; not Odo of Champagne, who, in fact, married her daughter. The mistakes hitherto prevailing as to Adelidis, render us less averse to suspect others of the same sort among the genealogists; and Wace's account of Muriel is confirmed from other sources. It would seem to have been to her, then a widow—ad Muriel sancti-monialem—sister of Odo, bishop of Bayeux—and therefore sister, or more properly half-sister of Adelidis, that the poet Serlon, the canon of Bayeux, (as to whom see Wace, ii. 235, 393) addressed his verses de captâ Bajocensium civitate. The baron here called Iwun-al-Chapel seems to be EUDO DE CAPELLO—du manteau, or capuchon—son of Turstain Halduc and Emma his wife, and subscribing himself Eudo Haldub in a charter of 1074. Mém. Ant. Norm. viii. 436. He was dapifer to duke William; although not the Eudo dapifer of Domesday, who was son of Hubert de Rie. He was the head of the house of Haie-du-Puits in the Cotentin, and undoubtedly married a Muriel, as appears by the charters of Lessay, whether she were a daughter of Herluin or not. The estates of Eudo went to his nephew, which confirms Wace's account of his having no issue. See the Lessay charters in Dugdale and Gallia Christiana, and our subsequent note on Haie.
