In 995, according to Symeon of Durham, when the remains of St Cuthbert were transferred from Chester-le-Street to Durham, Uhtred went to Durham with his monks to clear the site of the new cathedral. The new cathedral was founded by Bishop Aldhun, and Uhtred married Aldhun's daughter, Ecgfrida, probably at about this time. From his marriage he received several estates that had belonged to the church.[1]
