Auisle

Auisle or Óisle was a Viking leader in Ireland and Scotland in the mid-late ninth century. He was the son of the king of Lochlann, identified in the non-contemporary Fragmentary Annals of Ireland as Gofraid, and brother of Amlaíb Conung and Ímar, the latter of whom founded the Uí Ímair dynasty, and whose descendants would go on to dominate the Irish Sea region for several centuries. Another Viking leader, Halfdan Ragnarsson, is sometimes considered a brother. The Irish Annals title Auisle, Ímar and Amlaíb "kings of the foreigners". Modern scholars use the title "kings of Dublin" after the Viking settlement which formed the base of their power.
