Rǫgnvaldr Óláfsson was a twelfth-century King of the Isles, succeeding the warrior Somerled. He was a son of Óláfr Guðrøðarson, King of the Isles and a member of the Crovan dynasty. In the 1153, Óláfr was assassinated by three nephews, before his son, Guðrøðr, was able to overcome them and succeed his father as king. By 1158, Guðrøðr was forced from power by his brother-in-law, Somairle mac Gilla Brigte, who was married to Óláfr's daughter Ragnhildr. In 1164, when Somairle was killed in an invasion of Scotland, and while Guðrøðr was away in exile overseas, Rǫgnvaldr briefly seized the kingship for himself, before being overcome by Guðrøðr, who had him blinded and mutilated.
Óláfr Guðrøðarson, also known as Olaf the Black, was a thirteenth-century King of the Isles, and a member of the Crovan dynasty. He was a son of Guðrøðr Óláfsson, King of the Isles and Fionnghuala Nic Lochlainn. Óláfr was a younger son of his father; Óláfr's elder brother, Rǫgnvaldr, probably had a different mother. According to the Chronicle of Mann, Guðrøðr appointed Óláfr as heir since he had been born "in lawful wedlock". Whether or not this is the case, after Guðrøðr's death in 1187 the Islesmen instead appointed Rǫgnvaldr as king, as he was a capable adult and Óláfr was a mere child. Rǫgnvaldr ruled the island-kingdom for almost forty years, during which time the half-brothers vied for the kingship.
Haraldr Óláfsson was a thirteenth-century King of Mann and the Isles, and a member of the Crovan dynasty. He was one of several sons of Óláfr Guðrøðarson, King of the Isles, although the identity of his mother is uncertain. When his father died in 1237, Haraldr succeeded to the kingship as a fourteen-year-old, and held the kingship for about a decade afterwards.
The sovereign or feudal lordship of Argyle was the holding of the senior branch of descendants of Somerled (Somhairle), this branch becoming soon known as Clan MacDougall
Magnús Óláfsson was a King of Mann and the Isles. He was a son of Óláfr Guðrøðarson, King of the Isles, and a member of the Crovan dynasty. Magnús' realm encompassed Mann and parts of the Hebrides. Some leading members of Magnús' family—such as his father—styled themselves "King of the Isles"; other members—such as Magnús and his brothers—styled themselves "King of Mann and the Isles". Although kings in their own right, leading members of the Crovan dynasty paid tribute to the Kings of Norway and generally recognised a nominal Norwegian overlordship of Mann and the Hebrides. Magnus was driven out by King Alexander III.
Eóghan MacDubhghaill was a 13th-century Scottish nobleman and warrior who was styled "King of the Isles", "Lord of Argyll". He was the son of Donnchadh, son of Dubhghall, son of Somhairle mac Gille Brighde.
Alexander of Argyll, also known as Alexander of Lorne, and Alexander MacDougall, was a Scottish magnate from the late 13th and early 14th century.
Dubgall mac Somairle was an apparent King of the Isles. He was a son of Somairle mac Gilla Brigte and Ragnhildr Óláfsdóttir. Dubgall was a leading figure of Clann Somairle, and the eponymous ancestor of Clann Dubgaill. Dubgall's career is obscure, and little is certain of his life.
Aonghus Mór mac Domhnaill was a leading figure in the thirteenth-century kingdoms of the Isles and Scotland. He was a son of Domhnall mac Raghnaill, the eponym of Clann Domhnaill, a branch of Clann Somhairle. Aonghus Mór appears to have succeeded his father in the mid part of the thirteenth century. At the time, the rulers of the Isles were fiercely independent of the Scottish Crown, and owed nominal allegiance to the distant Norwegian Crown. Aonghus Mór's first certain appearance in the historical record seems to evince his involvement in aiding native Irish kindreds against the consolidation of Anglo-Irish authority in the north-west of Ireland. Such cooperation could have been undertaken in the context of overseas kindreds like Clann Domhnaill constructing Irish alliances to gain assistance against Scottish encroachment.
Ruaidhrí mac Raghnaill was a leading figure in the Kingdom of the Isles and a member of Clann Somhairle. He was a son of Raghnall mac Somhairle, and was the eponymous ancestor of Clann Ruaidhrí. Ruaidhrí may have become the principal member of Clann Somhairle following the annihilation of Aonghus mac Somhairle in 1210. At about this time, Ruaidhrí seems to have overseen a marital alliance with the reigning representative of the Crovan dynasty, Rǫgnvaldr Guðrøðarson, King of the Isles, and to have contributed to a reunification of the Kingdom of the Isles between Clann Somhairle and the Crovan dynasty.
Domhnall mac Raghnaill was a Hebridean noble in the late 12th and early 13th centuries. He is the eponymous progenitor of Clan Donald. For this reason some traditions accumulated around him in the later Middle Ages and early modern period. His vast impact on culture and in the centuries remains today. Despite his role as the historical figurehead of one of the world's most famous kindreds and surnames, there is almost no contemporary evidence yielding certain information about his life.
Alasdair Óg Mac Domhnaill was Lord of Islay and chief of Clann Domhnaill. He was the eldest son of Aonghus Mór mac Domhnaill, Lord of Islay. Alasdair Óg seems to first appear on record in 1264, when he was held as a hostage of the Scottish Crown for his father's good behaviour. During Alasdair Óg's career, the Scottish realm endured a succession crisis as a result of the unexpected death of Margaret, Maid of Norway, heir to the Scottish throne, in 1290. One of several factions that staked a claim to the throne was the Bruce kindred. Both Alasdair Óg and his father were cosignatories of the Turnberry Band, a pact that may have partly concerned the Bruces' royal aspirations.
Dubhghall mac Ruaidhrí was a leading figure in the thirteenth-century Kingdom of the Isles, on the West Coast of Scotland. He was a son of Ruaidhrí mac Raghnaill, and thus a member of Clann Ruaidhrí. Dubhgall was the last Gaelic King of Mann.
Aonghus mac Somhairle was a leading member of Clann Somhairle. He was a son of Somhairle mac Giolla Brighde, King of the Isles and Ragnhildr Óláfsdóttir. Other sons of Somhairle and Ragnhildr include Dubhghall, Raghnall, and possibly Amhlaoíbh. Aonghus' father was the common ancestor of Clann Somhairle. The succession of this kindred upon Somhairle's death is uncertain. The Clann Somhairle imperium appears to have spanned from Glenelg in the north, to the Mull of Kintyre in the south. It is possible that Aonghus came to rule in the north, with Dubhghall centred in Lorne, and Raghnall in Kintyre and the southern islands.
Clann Ruaidhrí was a leading medieval clan in the Hebrides and the western seaboard of Scotland. The eponymous ancestor of the family was Ruaidhrí mac Raghnaill, a principal member of Clann Somhairle in the thirteenth century. Members of Clann Ruaidhrí were factors in both the histories of the Kingdom of the Isles and the Kingdom of Scotland in the thirteenth- and fourteenth centuries. The family appears to have held power in Kintyre in the thirteenth century. By the fourteenth century, the family controlled an extensive provincial lordship stretching along north-western Scottish coast and into the Hebrides. As a leading force in the Kingdom of the Isles, the family fiercely opposed Scottish authority. With the collapse of Norwegian hegemony in the region, the family nimbly integrated itself into the Kingdom of Scotland.
The Gaelic surname Mac Somhairle means "son of Somhairle". The personal name Somhairle is a Gaelicised form of the Old Norse Sumarliðr and Sumarliði. The Old Norse Sumarliðr is composed of the elements sumar ("summer") and liðr ("seafarer"). As such, Sumarliðr and Sumarliði can be taken to mean "summer warrior", "summer seafarer". Anglicised forms of Mac Somhairle include: MacSorley, McSorley, Sorley, and Sorlie. Many settled in Ulster, hired as Gallowglass for Gaelic Kingdoms.
Haraldr Guðrøðarson was a mid thirteenth-century King of the Isles. He was the son of Guðrøðr Rǫgnvaldsson, King of the Isles, son of Rǫgnvaldr Guðrøðarson, King of the Isles. Haraldr Guðrøðarson and his predecessors were members of the Crovan dynasty, and ruled an island-kingdom that encompassed the Mann and portions of the Hebrides, variously known as the Kingdom of the Isles or the Kingdom of Mann and the Isles.
Ailéan mac Ruaidhrí was a leading figure in the thirteenth-century kingdoms of the Isles and the Scotland. He was a son of Ruaidhrí mac Raghnaill, and thus a member of the Clann Ruaidhrí branch of Clann Somhairle. Ailéan was a brother of Dubhghall mac Ruaidhrí, King of Argyll and the Isles, a significant figure who held power in the mid thirteenth century. At the time, the rulers of the Isles were fiercely independent of the Scottish Crown, and owed nominal allegiance to the distant Norwegian Crown. In 1259, Dubhghall's daughter married the son of King of Connacht, and Ailéan is recorded to have commanded the woman's tocher of one hundred and sixty gallowglass warriors.
Dubhghall mac Suibhne was a Scottish landholder in Argyll, and a leading member of Clann Suibhne. He was a son of Suibhne mac Duinn Shléibhe, and appears to have held lordship of Knapdale from at least the 1240s to the 1260s, and may have initiated the construction of Skipness Castle and Lochranza Castle.
