Olaf Cuarán Sitricsson ^{1 2}

   Other names for Olaf were Amlaíb Cuaran and Óláfr Kváran.

  General Notes:

Olaf Sihtricson or Olaf Kvaaran of Dublin (King of York & Iona).
Named (IN SAGAS) OLAF THE RED, OR OLAF CUARAN, OLAF also spelled ANLAF, king of the Danish kingdoms of Northumbria and of Dublin.

He was the son of Sihtric, king of Deira, and was related to the English king Aethelstan. When Sihtric died about 927 Aethelstan annexed Deira, and Olaf took refuge in Scotland and in Ireland until 937, when he was one of the leaders of the formidable league of princes that was destroyed by Aethelstan at the famous Battle of Brunanburh. Again he sought a home among his kinsfolk in Ireland, but just after Aethelstan's death in 940 he or Olaf Guthfrithson was recalled to England by the Northumbrians. Both crossed over, and in 941 the new English king, Edmund, gave up Deira to the former. The peace between the English and Danes did not, however, last long. Wulfstan, archbishop of York, sided with Olaf; but in 944 Olaf was driven from Northumbria by Edmund, and crossing to Ireland, Olaf ruled over the Danish kingdom of Dublin. From 949 to 952 he was again king of Northumbria, until he was expelled once more (this time by Erik Bloodaxe), and he passed the remainder of his active life in warfare in Ireland. But in 980 his dominion was shattered by the defeat of the Danes at the Battle of Tara. He went to Iona, where he died probably in 981, although one dubious account says he was in Dublin in 994.

There is some debate about which of his wives was the mother of which of his children.

  Noted events in his life were:

• Acceded: King of Dublin & York, 945.

• Abdicated: 980.

Olaf married Gormflaeth ingen Murchada MacFinn, daughter of Morugh MacFinn and Unknown. (Gormflaeth ingen Murchada MacFinn died in 1030.)

Olaf next married daughter of Scotland, daughter of Constantine II of Scotland and Unknown, in 937.
