Duncan was the "Ruler of Strathclyde" until his accession to the throne of Scotland.
Duncan I ruled as King of Scotland from 1034 untiol 1040.
King Duncan lost his crown, and his life, on 14 August 1040 when he was killed by his general, the legendary Macbeth the Mormaer of Moray. It is assumed that he was buried with the other Scottish kings at the Monastery at Iona.
Crínán of Dunkeld (died 1045) was the lay abbot of the diocese of Dunkeld, and perhaps the Mormaer of Atholl. Crínán was progenitor of the House of Dunkeld, the dynasty who would rule Scotland until the later 13th century.
Crinán was married to Bethoc, daughter of King Malcolm II of Scotland (reigned 1005-1034). As Malcolm II had no son, the strongest hereditary claim to the Scottish throne descended through Bethóc, and Crinán's eldest son Donnchad I (reigned 1034-1040), became King of Scots. Some sources indicate that Malcolm II designated Duncan as his successor under the rules of tanistry because there were other possible claimants to the throne. - [1]
