List of Famous people with last name Gu-r-arson

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.

Rǫgnvaldr Guðrøðarson ruled as King of the Isles from 1187 to 1226. He was 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 chose Rǫgnvaldr, who was likely Óláfr's half-brother. Rǫgnvaldr went on to rule the Kingdom of the Isles for almost forty years before losing control to Óláfr.

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.
