“ EDRIC, or Eadric, STREONA (d. 1017) , ealdorman of the Mercians, was a man of ignoble birth who was advanced to high dignity through the favour of the English king Æthelred II. In 1007 he became ealdorman of the Mercians, and subsequently married Æthelred’s daughter Eadgyth. In the struggle between the English and the Danes he appears in the character of an arch-traitor. When Æthelred in 1009 proposed a great attack on the Danes, Edric dissuaded him from carrying it into effect. Again, on the invasion of England by Canute in 1015 Edric deserted Edmund Ironside and joined him. ”
