Bethóc was the eldest daughter and heir of Malcolm II of Scotland, who had no known sons. She married Crínán, Abbot of Dunkeld, about 1000.[1][2] This marriage may have been designed to encourage the Dunkeld's clan to remain loyal to Malcolm II.[3]
Together, Bethóc and Crínán had an heir, Donnchad I.[4] Crínán has also been assigned other children, that may have been by Bethóc: Maldred, Lord of Allerdale, married Ealdgyth, daughter of Uhtred the Bold, and ancestor of the Earls of Dunbar; and a daughter (name not known) mother of Moddan, Earl of Caithness.[5] Their heir Duncan, also known as Donnchad, succeeded his grandfather Malcolm II to become King of Alba in 1034.[6]
Bethóc may have had two younger sisters: the woman (named by Hector Boece as Donada) who married Findláech mac Ruaidrí, Mormaer of Moray, and was the mother of Macbeth; and an unnamed woman who according to Orkneyinga Saga married Sigurd Hlodvirsson, Earl of Orkney and was the mother of Thorfinn the Mighty.[7] Early writers have asserted that Máel Coluim also designated Donnchad as his successor under the rules of tanistry because there were other possible claimants to the throne.
