King Malcolm II was the last of the ancient [dynasty] line of the House of MacAlpin. Malcolm, was much respected by his contemporaries, the Irish Annals refer to him as 'honoured among all men.'
He had succeeded to Scotland's throne after killing his predeccesor, Kenneth III in battle at Monzievaird, to the north of Crieff, on 25th March, 1005. Kenneth's son, Giric, was also killed in the battle. Malcolm later had Kenneth's grandson killed to ensure the succession of his grandson Duncan I, son of his daughter Bethoc, as his successor.

Wikipedia list three daughters; Bethóc, Donada, Olith

Wikipedia also writes, “since Malcolm had no son of his own, he undertook to negotiate a series of dynastic marriages of his three daughters to men who might otherwise be his rivals, while securing the loyalty of the principal chiefs, their relatives. First he married his daughter Bethoc to Crinan, Thane of The Isles, head of the house of Atholl and secular Abbot of Dunkeld; then his youngest daughter, Olith, to Sigurd, Earl of Orkney. His middle daughter, Donada, was married to Finlay, Earl of Moray, Thane of Ross and Cromarty and a descendant of Loarn of Dalriada. This was risky business under the rules of succession of the Gael, but he thereby secured his rear and, taking advantage of the renewal of Viking attacks on England, marched south to fight the English”.

According to:
http://www.undiscoveredscotland.co.uk/usbiography/monarchs/malcolmii.html
Malcolm's three daughters had between them produced three notable sons. One married Earl Sigurd of Orkney, and their son Earl Thorfinn went on to bring much of Caithness and Sutherland into Scotland. One married Crínán, the Abbot of Dunkeld, and their son Duncan went on to succeed Malcom II as Duncan I. And the third married Findlàech, the sub-king of Moray, and their son Macbeth went on to kill Duncan (with Thorfinn's help) and become King Macbeth.
