Title: Máel Snechtai of Moray
Content:  Máel Snechtai of Moray (or Máel Snechtai mac Lulaich) was the ruler of Moray, and, as his name suggests, the son of Lulach, King of Scotland. He is called on his death notice in the Annals of Ulster, "Máel Snechtai m. Lulaigh ri Muireb" (="Máel Snechtai, Lulach's son, King of Moray"), which is a significant terminological development, since previously the titles for the ruler of Moray had either been "King of Scotland" or "Mormaer." The title is repeated for his successor, Óengus (if indeed the latter were his successor). Perhaps then the events of Máel Snechtai's death caused some kind of identity disassociation between the Men of Moray and the Men of Scotland. The Anglo-Saxon Chronicle, s.a. 1078, reports that "In this year Máel Coluim seized the mother

Content:  Máel Snechtai ...and all his treasures, and his cattle; and he himself escaped [only] with difficulty." The ... represents a lacuna in the text one line long; but it is clear that Máel Snechtai was defeated by King Máel Coluim III in some kind of conflict. Grant's suggestion that Máel Snechtai subsequently retired to a monastery is based only on textual innuendo, and is made unlikely by the fact that he was called "King of Moray" on his death. Máel Snechtai, as the son of King Lulach, undoubtedly perceived himself as the rightful king of Scotland, and the already noted conflict with Máel Coluim III strongly suggests that he pursued his claim. His death date is based on the year given by the Annals of Ulster, s.a. 1085.
Title: Máel Petair of Mearns
Content:  Máel Petair of Mearns is the only known Mormaer of the Mearns. His name means "tonsured one of (Saint) Peter". Professor Dauvit Broun of the University of Glasgow identifies his father as a man called Loren. Little is known of him except that, in 1094, he is said to have killed King Duncan II of Scotland, suggesting he was an associate of Donald III of Scotland.

Lulach's son, Mael Snechtai, died in 1085 as 'king of Moray'. Later, an earl named Aed or 'Heth' who witnesses royal charters early in the next century may also have been based in Moray. The last ruling member of the dynasty, styled 'king' or 'earl' of Moray, was Óengus (Angus) son of the daughter of Lulach. Óengus (Angus) challenged David I of Scotland in battle, but was defeated and killed at Stracathro in Angus, in 1130 and thus the Kingdom of Moray was destroyed by 
Title: Máel Sechnaill mac Máele Ruanaid
Content:  Máel Sechnaill mac Máele Ruanaid (Modern Irish: Maolsheachlann Mac Maolruanaidh), also known as Máel Sechnaill I, anglicised as Malachy MacMulrooney (died 27 November 862) was High King of Ireland. The Annals of Ulster use the Old Irish title rí hÉrenn uile, that is "king of all Ireland", when reporting his death, distinguishing Máel Sechnaill from the usual Kings of Tara who are only called High Kings of Ireland in late sources such as the Annals of the Four Masters or Geoffrey Keating's Foras Feasa ar Éirinn. According to the "Grand History of the Celts", a traditional book of facts and folklore, Mael Sechnaill was the husband of Mael Muire, the granddaughter of the legendary Alpin, a 9th-century king of Dalriada.
Title: Máel Sechnaill mac Domnaill
Content:  Máel Sechnaill belonged to the Clann Cholmáin branch of the Uí Néill dynasty. He was the grandson of Donnchad Donn, great-grandson of Flann Sinna and great-great-grandson of the first Máel Sechnaill, Máel Sechnaill mac Máele Ruanaid. The Kings of Tara or High Kings of Ireland had for centuries alternated between the various Uí Néill branches. By Máel Sechnaill's time this alternating succession passed between Clann Cholmáin in the south and the Cenél nEógain in the north, so that he succeeded Domnall ua Néill in 980. This system had survived previous challenges by outsiders including the kings of Ulster, Munster and Leinster, and the Viking invasions.
Title: Diarmait mac Máel na mBó
Content:  Diarmait belonged to the Uí Cheinnselaig, a kin group of south-east Leinster centred on Ferns. His father, Donnchad mac Diarmata, became known more commonly by the epithet Máel na mBó ("Baldy of the Cattle"), whence Diarmait's patronym. The last of Diarmait's ancestors to have been counted as king of all Leinster, Crimthann mac Énnai, died in the late 5th century; but Diarmait's more immediate forebears, most recently his great-grandfather Domnall mac Cellaig (died 974), had been counted among the kings of the Uí Cheinnselaig. Diarmait's mother was Aife, daughter of Gilla Pátraic mac Donnchada, king of Osraige. He had at least one sibling, a brother named Domnall whose son Donnchad mac Domnaill Remair later became king of Leinster. The Uí Cheinnselaig had been

The pedigree of Macbeth from the Loarn kings of Dál Riata offers a clue to the origins of his dynasty in Moray. Moray may have been a separate kingdom for a time, independent of the dynasty of Kenneth mac Alpin. However it seems likely that rulers of Moray were subject loosely to the Kings of Alba. Moray acted as a buffer against further Scandinavian penetration from the north, and its rulers were remembered with respect in Scandinavian sources such as Orkneyinga Saga. Macbeth himself was in turn

After Lulach was killed and succeeded by Máel Coluim mac Donnchada of the House of Dunkeld, Lulach's son Máel Snechtai and grandson Óengus continued to rule Moray and challenge the kings to the south until Óengus' defeat and death at the Battle of Stracathro in 1130. Over the following decades David I of Scotland and his successors established institutions to bring Moray more directly under Scottish control, suppressing the office of mormaer, founding monasteries, burghs and sheriffdoms within the province, and granting large areas of it as provincial lordships to loyal followers. However Moray continued to be a base for rebellions by the Meic Uilleims, the descendents of the last mormaer William fitz Duncan, until the last of the line was killed in 1230.
