[iv] Historians dispute the origins of the House of Godwin. A combination of limited and sometimes unreliable documentary evidence, Norman and post-Norman propaganda, internal rivalries within the House of Wessex (in particular as between Alfred and his descendants and those of his elder brother and predecessor as King of Wessex, Aethelred I, from whose elder son, Aethelhelm (see below), the Godwins are said to be descended, founding their claim to the English throne) and vested interests.
The Godwin line of the House of Wessex: Aethelred I (grandson of Ecgberht and fourth son of Æthelwulf, was king of the West Saxons 865 – 871 and was married to Wulfthryth (regina)), Aethelhelm (? ealdorman of Wiltshire, died 898), Aethelfrith (ealdorman occ. 901 – 924), Eadric (ealdorman occ. 925 – 949), Aethelweard ‘the historian’ (ealdorman of the western provinces occ. 956 – 998), Aethelmaer Cild (ealdorman of the western provinces occ. 1005 – 15), Wulfnoth Cild (thegn of Sussex, occ. 1009, died in or before 1014), Godwin (earl of Wessex, died 1053), father of Harold II Godwinson.
