The Annals of Ulster:

" Amlaíb, son of the king of Lochlann [Laithlinde], came to Ireland, and the foreigners of Ireland submitted to him, and he took tribute from the Irish."


Amlaíb Conung is written in the Annals to be the son in law of Aedh Finnliath MacNeill, who is recorded to have been married to Mael Muire, the daughter of Cinead MacAilpin " Kenneth MacAlpin" ( Died Feb 13,858).
