According to the earliest life of St Dunstan, written around the year 1000, Eadwig left the banquet which followed his coronation in Kingston upon Thames, and was found cavorting with a noblewoman named Æthelgifu and her daughter.
Dunstan dragged him back to the banquet, earning the enmity of Eadwig and the two women, and at Æthelgifu's instigation Dunstan was deprived of his abbacy of Glastonbury and forced into exile.

The contemporary record of the Anglo-Saxon Chronicle reports Eadwig's accession and Dunstan fleeing England, but does not explain why Dunstan fled.
Thus this report of a feud between Eadwig and Dunstan could either have been based on a true incident of a political quarrel for power between a young king and powerful church officials who wished to control the king and who later spread this legend to blacken his reputation, or it could be mere folklore; the Chronicle also tells of Oda putting aside the King's marriage on the grounds Eadwig and his wife were "too related".

The account of the quarrel with Dunstan and Cynesige, bishop of Lichfield at the coronation feast is recorded in the Anglo-Saxon Chronicle and in the later chronicle of John of Worcester and was written by monks supportive of Dunstan's position.
The "cavorting" in question consisted of Eadwig (then only 16) being away from the feast with Ælfgifu and her mother Æthelgifu.
He later married Ælfgifu, who seems to have been the sister of Æthelweard the Chronicler.
Æthelweard describes himself as the "grandson's grandson" of King Æthelred I. Eadwig was the son of King Edmund the Magnificent, grandson of King Edward the Elder, great-grandson of King Alfred the Great, and therefore great-great-nephew of King Æthelred I. Eadwig and Ælfgifu were therefore third cousins once removed.
