Edmund Ironside King Of England
- Born: 989, Wessex, England
- Marriage: Ealdgyth Morcarson Queen Consort in 1015 in Malmsbury, Wiltshire, England
- Died: 30 Nov 1016, London, Middlesex, England aged 27
In the late summer of 1015, at some time between 15 August and 8 September, Edmund Ironside raised a revolt against his father King Æthelred. Either then, or perhaps even earlier, he removed Sigeferth's widow from Malmesbury, against his father's wishes, and married her. Sigeferth and Morcar's friends and allies supported Edmund after this. While two charters issued by Edmund which mention his wife survive from about this time, neither of them contain her name in the surviving texts.
It is generally, but not universally, supposed that Ealdgyth, if that was her name, was the mother of Edmund Ironside's sons. These were Edmund, who died young in exile, and Edward the Exile, who returned to England late in the reign of his uncle King Edward the Confessor and died soon afterwards. Whether she went into exile with her children following Edmund's death in 1016 is unknown.
One reason advanced for supposing that John of Worcester may have been mistaken in naming this woman Ealdgyth is that Sigeferth's brother Morcar had also been married to a woman named Ealdgyth. This Ealdgyth was the daughter of Ælfthryth, and niece of Ælfhelm, Ealdorman of York and Wulfric Spot . While Ealdgyth is a common female name in the period, this coincidence has raised the suspicion that the Worcester chronicler has confused Sigeferth's widow with his sister-in-law.
Edmund had a relationship with Ealdgyth Morcarson Queen Consort, daughter of Morcar England and Edgitha Of England, in 1015 in Malmsbury, Wiltshire, England. (Ealdgyth Morcarson Queen Consort was born about 992 in Wessex, England and died about 1016 in London, Middlesex, England.)
