`  :Since I wrote the Amlaíb article, I've read Hudson's Oxford DNB article http://www.oxforddnb.com/index/101049263/ which comments ``The career of Óláf the White corresponds with that of the Olaf ‘son of the king of Lochland’ (Norway) (d. 875), also known as Óláf, king of Dublin (c.853–871), whose activities are recorded in the Irish chronicles; many scholars consider them to be the same individual. They were active at the same time, in the same place, and were recognized as the leaders of the vikings in Ireland.``  :Likewise, Alex Woolf in Pictland to Alba (p. 282) says ``It has long been noted that Óláfr the White must be, or at the very least must draw some of his attributes from the Amlaíb son of the king of Laithlind who first appears in the Irish sources in 853 and whom the Chronicle of the Kings of Alba seems to say was kiled by Constantín son of Cináed in Pictavia (c. 871-2).`` :Would you have access to Helle's Cambridge History of Scandinavia? Would be nice to know what, if anything, that says about Olaf. I understand that some people identify Olaf the White and some other saga-Olafs. Any ideas on that?    `
