  RESEARCH NOTES:
  1034-1040: King of Scots [Ref: Tapsell p180, Weis AR #170]
  King of Scots [Ref: Moncreiffe p20]
  1018-1034: King of Strathclyde [Ref: Paget p153]
  1034: King of Scots [Ref: Paget p153]
  
  1034: Duncan, the son of Crinan, abbot of Dunkeld, and Bethoc, daughter
  of Malcolm, the son of Kenneth, reigned six years [Ref: Weis AR #170]
  
  1038 or 1039: Ealdred, Earl of Northumbria, invaded Strathclyde, perhaps in an
  attempt to wrest it from the Scots.  Duncan responded in 1040 with an attack
  on Durham.  Like his grandfather's attack in 1006, it ended in disaster, with
  Scottish forces fleeing, and Scottish heads decorating the Durham marketplace.
  This defeat seems to hae weakened his authority so severely that Macbech of
  the Cenel Loairn was able to defeat and kill him in battle near Elgin [Ref:
  Davidson 1995]
  
  murdered by Macbeth near Elgin [Ref: Weis AR #170] killed by cousin & successo
  Macbeth [Ref: Moncreiffe p20]
  
  marriage to Sibyla, a relative of Earl Siward of Northumbria, provided
  Duncan's son Malcolm a valuable allay in his efforts to wrest the Scottish
  kingship from Macbeth [Ref: Davidson 1995]
