Ethelred of Scotland

Ethelred (died c. 1093 Edelret mac Maíl Coluim or Æthelred Margotsson) was the son of King Malcolm III of Scotland (Gaelic Máel Coluim III) and his wife Margaret of Wessex, the third oldest of the latter and the probable sixth oldest of the former. He took his name, almost certainly, from Margaret's great-grandfather Æthelred the Unready. He became the lay abbot of Dunkeld.
