collected by the chamber, one of the household departments. William cultivated close relations with the church in his duchy. He took part in church councils and made several appointments to the Norman episcopate, including the appointment of Maurilius as Archbishop of Rouen. Another important appointment was that of William's half-brother, Odo, as Bishop of Bayeux in either 1049 or 1050. He also relied on the clergy for advice, including Lanfranc, a non-Norman who rose to become one of William's prominent ecclesiastical advisors in the late 1040s and remained so throughout the 1050s and 1060s. William gave generously to the church; from 1035 to 1066, the Norman aristocracy founded at least twenty new monastic houses, including William's two monasteries in Caen, a remarkable expansion of religious life in the duchy. English and continental concerns In 1051 the childless King Edward of England appears to have chosen William as his successor. William was the grandson of Edward's maternal uncle, Richard II of Normandy. The Anglo-Saxon Chronicle, in the "D" version, states that William visited England in the later part of 1051, perhaps to secure confirmation of the succession, or perhaps William was attempting to secure aid for his troubles in Normandy. The trip is unlikely given William's absorption in warfare with Anjou at the time. Whatever Edward's wishes, it was likely that any claim by William would be opposed by Godwin, Earl of Wessex, a member of the most powerful family in England. Edward had married Edith, Godwin's daughter, in 1043, and Godwin appears to have been one of the main supporters of Edward's claim to the throne. By 1050, however, relations between the king and the earl had soured, culminating in a crisis in 1051 that led to the exile of Godwin and his family from England. It was during this exile that Edward offered the throne to William. Godwin returned from exile in 1052 with armed forces, and a settlement was reached between the king and the earl, restoring the earl and his family to their lands and replacing Robert of Jumièges, a Norman whom Edward had named Archbishop of Canterbury, with Stigand, the Bishop of Winchester. No English source mentions a supposed embassy by Archbishop Robert to William conveying the promise of the succession, and the two Norman sources that mention it, William of Jumièges and William of Poitiers, are not precise in their chronology of when this visit
