 In 1015 Sigeferth (died 1015) and Morcar came to an assembly in Oxford, probably hoping for a royal pardon, but they were murdered by Eadric Streona.King Æthelred then ordered that Sigeferth's widow, Ealdgyth, be seized and brought to Malmesbury Abbey, but Edmund seized and married her in defiance of his father, probably to consolidate his power base in the East Midlands.He then received the submission of the people of the Five Boroughs.
