to in late 11th century Icelandic saga material as a son of the powerful Ragnar Lodbrok. This Ivar had 11 brothers including Halfdan Ragnarsson and Ubba (but not including an Amlaib or Óisle) and is also believed to have died childless. Nor is there any indication in the Irish annals that Ragnar Lodbrok had any Irish connections. Amlaib Amlaib had two sons, Oistin (d. 875) and Carlus (d. 868). Unlike Ímar, no later descendants are recorded but like his brother, he has also been identified as a saga character — Olaf the White.Crawford (1987), p. 192. This Olaf married Aud the Deep-Minded, daughter of Ketil Flatnose and they had a son, Thorstein the Red, whose name is similar to the Irish "Oistin". However, Aud does not appear in the Irish sources and there are various problems with the connection. For example, the Landnámabók has Olaf killed in battle in Ireland, but no Irish source refers to the battle and the Chronicle of the Kings of Alba has Amlaib dying in Pictavia at the hands of Causantín mac Cináeda. The connection has "frequently been proposed and frequently been rejected". References Notes Footnotes General references Adam of Bremen. Gesta Hammaburgensis Ecclesiae Pontificum in Francis J.
