or ÆTHELMARE, Earl of Cornwall and Devonshire in the reign of King Edgar. It is not known of what family he was. His authority and riches were great, and so also in appearance was his piety. He founded the abbey of Cerneil, in Dorsetshire; and had so great a veneration for Eadwald, the brother of St Edmund the Martyr, who had lived a hermit in that country, near the Silver Well, that, with the assistance of Archbishop Dunstan, he translated his relics to the old church of Cerneil. In 1016, when Canute invaded England, Earl Ailmer, together with the traitorous Eadric Streone, Earl of Mercia, and Earl Algar, joined the Dane against their natural prince, Edmund Ironside, which contributed greatly to the ruin of the Saxon cause. Ailmer died not long after.
