The House of Moray or Clann Ruaidrí is a historiographical and genealogical construct to illustrate the succession of rulers whose base was in Moray and who ruled sometimes a larger kingdom. Clann Ruaidri has been claimed to have been descended in the male line from the Cenél Loairn, one of the ruling kindreds of Gaelic Dál Riata, based on a genealogy of Máel Snechtai reproduced in four Irish manuscripts. This genealogy has now been shown to be a clear and chronologically impossible fabrication made in the 11th or 12th centuries, constructed by joining three existing genealogies together. The pedigree lists only one further name beyond the ancestors of Máel Snechtai already identifiable from annalistic sources - that of Domnall, the father of Ruaidrí, who was the father of Findláech of Moray. The immediate ancestor of Domnall is given as Mongán mac Domnaill, who in fact died , over three centuries before the death of Findláech in 1020. At the times when the rival house held the throne, the Moray leaders usually had their effectively independent state of Moray, where a succession of kings (kinglets) or mormaers ruled. The succession followed quite loyally the rules of tanistry, resulting in practice to outcomes where branches of the leaders' extended family rotated on the rulership, possibly keeping a balance between important branches. This is quite typical for tribal societies, where primogeniture is much less usual than agnatic seniority or turns on the throne. For example, Macbeth, King of Scotland descended from one branch, and his stepson Lulach from another. Kings of Scots Following the death of Donnchad mac Crínáin in 1040, two members of the kindred ruled as Kings of Scots. Mac Bethad mac Findláich (1040–1057), ardri Alban Lulach mac Gillai Comgain (1057–1058), ri Alban Additionally, Giric mac Dúngail (878–889) may have been a member of this kindred. Already MacBeth's father and cousin (Lulach's uncle) had been "kings of Alba": Findlaich mac Ruaidhri, ri Alban, killed 1020 Mael Coluim mac Mael Brighdi mac Ruaidrí, rí Alban (1020-1029) Lulach's son and grandson were, however, titled kings of Moray, not of Alba: Mael Snechtai mac Lulaich, ri Muireb Oengus mac inghine Lulaich, ri Moréb (killed 1130) Mormaers of Moray Óengus of Moray (died 1130), who has no attestation of descending in male line from Cenel Loairn clan (he was son of daughter of Lulach), is the last known member of the kindred to have ruled
