 The question of St Edith's historical identity is fraught with difficulties.The tradition which was written down at the monastery of Bury St Edmunds in the 12th century and was later re-told by Roger of Wendover (d. 1236) and Matthew Paris (d. 1259) asserts that she was a sister of King Æthelstan, who gave her in marriage to Sihtric Cáech, a hiberno-scandinavian King of southern Northumbria and Dublin.It then suggests that the marriage was never consummated.
