Quibus expletis, astante ibidem sacrosancto corpore beati Bertini, cum aliis reliquiis, decretum est et exclamatum, ut, quicumque supramemoratam conventionem aliquando violare presumeret, eterno anathemati subjaceret, nisi digna penitencia reconciliatus, a tanto errato cito resipisceret. Fiat, fiat.
Arnulf and Gerbodo named in this charter were doubtless the sons of Gerbodo earl of Chester and of Ada his wife, the original grantors of the third part of the vill of Audreselles, and the fact of their becoming the men of the abbot is a strong proof of the truth of their father's history as told by Oderic Vitalis, which had resulted in the loss of his title of avoué of the abbey of St. Bertin.

In that year, according to the Chronicle of Tours, William duke of Normandy married Matilda, the divorced wife of Gerbodo, the mother of the children named above. The charter of William Warren, in the reign of William Rufus, who had created him earl of
