Rǫgnvaldr Óláfsson was a twelfth-century King of the Isles. 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.
Godred Crovan, known in Gaelic as Gofraid Crobán, Gofraid Meránach, and Gofraid Méránach, was a Norse-Gaelic ruler of the kingdoms of Dublin and the Isles. Although his precise parentage has not completely been proven, he was certainly an Uí Ímair dynast, and a descendant of Amlaíb Cúarán, King of Northumbria and Dublin.
Lǫgmaðr Guðrøðarson was a late eleventh-century King of the Isles, whose rise, reign, and fall from power are obscure. He was the eldest son of Guðrøðr Crovan, King of Dublin and the Isles, a Norse-Gaelic dynast who conquered and ruled the kingdoms of the Isles and Dublin, before dying in 1095. Three years after the latter's death, the Isles was conquered by Magnús Óláfsson, King of Norway, whose regime in the region lasted until his death in 1103. The chronology of Lǫgmaðr's reign is uncertain: he may have begun his reign either before Magnús' conquest, during his regime, or after his demise.
The Battle of Renfrew was fought between the Kingdom of the Isles and the Kingdom of Scotland in 1164, near Renfrew, Scotland. The men of the Isles, accompanied by forces from the Kingdom of Dublin, were commanded by Somerled. The identity of the Scottish commander is unrecorded and unknown. Herbert, Bishop of Glasgow, Baldwin, Sheriff of Lanark/Clydesdale, and Walter fitz Alan, Steward of Scotland are all possible candidates for this position. The battle was a disaster for the Islesmen and Dubliners. Somairle was slain in the encounter, apparently by local levies, and his forces were routed.
Óláfr Guðrøðarson was a twelfth-century King of Mann and the Isles. As a younger son of Guðrøðr Crovan, King of Dublin and the Isles, Óláfr witnessed a vicious power struggle between his elder brothers in the aftermath of their father's death. At some point, the young Óláfr was entrusted to the care of Henry I, King of England, and like the contemporaneous Scottish monarchs, Alexander I and David I, Óláfr appears to have been a protégé of the English king. As King of the Isles, Óláfr contracted marital alliances with neighbouring maritime rulers. Although he appears to have overseen successful military operations to reclaim the northernmost territories once controlled by his father, he may have witnessed the loss of authority in Galloway as well. Like his counterpart David I, Óláfr was a reformer and moderniser of his realm. However, his four-decade reign ended in abrupt disaster when he was assassinated by three nephews in 1153. Following the ensuing power struggle, Óláfr's son Guðrøðr overcame the kin-slayers, and assumed the kingship of the Kingdom of the Isles.
Guðrøðr Óláfsson was a twelfth-century ruler of the kingdoms of Dublin and the Isles. Guðrøðr was a son of Óláfr Guðrøðarson, King of the Isles and Affraic, daughter of Fergus, Lord of Galloway. Throughout his career, Guðrøðr battled rival claimants to the throne, permanently losing about half of his realm to a rival dynasty in the process. Although dethroned for nearly a decade, Guðrøðr clawed his way back to regain control of a partitioned kingdom, and proceeded to project power into Ireland. Although originally opposed to the English invasion of Ireland, Guðrøðr adeptly recognised the English ascendancy in the Irish Sea region and aligned himself with the English. All later kings of the Crovan dynasty descended from Guðrøðr.
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.
Ragnall mac Somairle was a significant late twelfth century magnate, seated on the western seaboard of Scotland. He was probably a younger son of Somairle mac Gilla Brigte, Lord of Argyll and his wife, Ragnhildr, daughter of Óláfr Guðrøðarson, King of the Isles. The twelfth-century Kingdom of the Isles, ruled by Ragnall's father and maternal-grandfather, existed within a hybrid Norse-Gaelic milieu, which bordered an ever strengthening and consolidating Kingdom of Scots.
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.
Ingimundr, also known as Ingimund, and Ingemund, was an eleventh-century delegate of Magnús Óláfsson, King of Norway. In the last decade of the eleventh century, Ingimundr was tasked by Magnús to take control of the Kingdom of the Isles. The realm had descended into utter chaos after the death of Guðrøðr Crovan, King of the Isles in 1095, which was followed by kin-strife amongst Guðrøðr's descendants, and the encroachment of Irish authority into the region. Ingimundr and his followers were slain in Lewis by the leading Islesmen whilst he was in the midst of securing the kingship. The following year, Magnús took matters into his own hands, and personally oversaw the conquest of the Isles himself.
Guðrøðr Rǫgnvaldsson, also known as Guðrøðr Dond, was a thirteenth-century ruler of the Kingdom of the Isles. He was a member of the Crovan dynasty, and a son of Rǫgnvaldr Guðrøðarson, King of the Isles, the eldest son of Guðrøðr Óláfsson, King of Dublin and the Isles. Although the latter may have intended for his younger son, Óláfr, to succeed to the kingship, the Islesmen instead settled upon Rǫgnvaldr, who went on to rule the Kingdom of the Isles for almost forty years. The bitterly disputed royal succession divided the Crovan dynasty for three generations, and played a central role in Guðrøðr's recorded life.
Roolwer, also known as Hrólfr, was an eleventh-century ecclesiast. He is the first named bishop of a jurisdiction which later became the Diocese of the Isles, and appears to have served at his post before, and perhaps during, the reign of Gofraid Crobán, King of Dublin and the Isles. Roolwer's name appears to correspond to the Old Norse Hrólfr, which could mean that he is identical to either of two contemporary like-named bishops of Orkney. Roolwer's predecessor in the Isles may have been Dúnán, whose death in 1074 during the Dublin overlordship of Toirdelbach Ua Briain, King of Munster, may have enabled the ecclesiastical separation of Dublin from the Isles. The site of Roolwer's cathedral is unknown, although Maughold and St Patrick's Isle are possibilities.
Fingal mac Gofraid, and his father, Gofraid mac Sitriuc, were late eleventh-century rulers of the Kingdom of the Isles. Although one source states that Gofraid mac Sitriuc's father was named Sitriuc, there is reason to suspect that this could be an error of some sort. There is also uncertainty as to which family Gofraid mac Sitriuc belonged to. One such family, descended from Amlaíb Cúarán, King of Northumbria and Dublin, appears to have cooperated with Diarmait mac Maíl na mBó, King of Leinster. Another family, that of Echmarcach mac Ragnaill, King of Dublin and the Isles, opposed Amlaíb Cúarán's apparent descendants, and was closely connected with Diarmait's adversaries, the Uí Briain kindred.
Gofraid mac Amlaíb meic Ragnaill was a late eleventh-century King of Dublin. Although the precise identities of his father and grandfather are uncertain, Gofraid was probably a kinsman of his royal predecessor, Echmarcach mac Ragnaill, King of Dublin and the Isles. Gofraid lived in an era when control of the Kingdom of Dublin was fought over by competing Irish overlords. In 1052, for example, Echmarcach was forced from the kingdom by the Uí Chennselaig King of Leinster, Diarmait mac Maíl na mBó. When the latter died in 1072, Dublin was seized by the Uí Briain King of Munster, Toirdelbach Ua Briain, a man who either handed the Dublin kingship over to Gofraid, or at least consented to Gofraid's local rule.
Ímar mac Arailt was an eleventh-century ruler of the Kingdom of Dublin and perhaps the Kingdom of the Isles. He was the son of a man named Aralt, and appears to have been a grandson of Amlaíb Cuarán, King of Northumbria and Dublin. Such a relationship would have meant that Ímar was a member of the Uí Ímair, and that he was a nephew of Amlaíb Cuarán's son, Sitriuc mac Amlaíb, King of Dublin, a man driven from Dublin by Echmarcach mac Ragnaill in 1036.
Domnall mac Taidc was the ruler of the Kingdom of the Isles, the Kingdom of Thomond, and perhaps the Kingdom of Dublin as well. His father was Tadc, son of Toirdelbach Ua Briain, King of Munster, which meant that Domnall was a member of the Meic Taidc, a branch of the Uí Briain. Domnall's mother was Mór, daughter of Echmarcach mac Ragnaill, King of Dublin and the Isles, which may have given Domnall a stake to the kingship of the Isles.
Nicholas was a twelfth-century Bishop-elect of the Isles. There is no evidence that he was ever consecrated.
