Overview
Ecgwynn or Ecgwynna (Old English Eċġwynn, lit. "sword joy"; fl. 890s), was the first consort of Edward the Elder, later King of the English (reigned 899–924), by whom she bore the future King Æthelstan (r. 924–939), and a daughter who married Sihtric Cáech, Norse king of Dublin, Ireland, and Northumbria. Almost nothing is known about her background and life. Not even her name is given in any sources until after the Norman Conquest. The first to record it is William of Malmesbury, who presents it in Latinised guise as Egwinna and who is in fact the principal source for her existence.
Life as consort
According to William of Malmesbury, Æthelstan was thirty years old when he became king in 924, which would mean that he was born around 894 and Ecgwynn's marriage to Edward the Elder took place in about 893. By this time, Edward had reached majority and one of his priorities would have been to secure the continuation of Alfred's line. No sources report what became of Ecgwynn afterwards, though two events are directly relevant. First, William writes that on King Alfred's instigation, Æthelstan was sent to be raised at the Mercian court of his aunt Æthelflæd. Second, it is known that by 901, Edward had taken to wife Ælfflæd, a daughter of ealdorman Æthelhelm. The reason for this decision is unclear. It may have simply been that Ecgwynn was no longer alive in 899 and that it was therefore only natural that Edward looked for another bride. It is also possible that Edward's first marriage was thought to lack the political import that was needed to buttress his position as king of the English. Alfred may have been responsible for arranging the first marriage and so his death in 899 would have afforded Edward and his counsellors room to follow a different course.
An anonymous daughter
The Anglo-Saxon Chronicle records that King Æthelstan married his sister to Sihtric Cáech (died 927), king of Northumbria, and that the nuptials were celebrated at the Mercian royal centre at Tamworth on 30 January 926. William notes that she was Ecgwynn's daughter, but was unable to discover her name in any of the sources available to him. It is only later sources which offer suggestions, whose value remains uncertain. Roger of Wendover (died 1236) and Matthew Paris (died 1259) thought that she was the St Edith (Eadgyth) who according to the Old English saints' list known as Secgan, was buried at the nunnery of Polesworth (Warwickshire), not far from Tamworth.
