Two wives of Amlaíb are mentioned by the annals. The first, an unnamed daughter of Áed Findliath is mentioned in passing by the Fragmentary Annals with regards to an alliance between Amlaíb and Áed.[35] Elsewhere the Fragmentary Annals, when reporting the death of Auisle, refer to "the daughter of Cináed" as Amlaíb's wife.[73] It has been suggested that the reference to Áed is mistaken, and that Amlaíb's wife was a daughter of Cináed mac Conaing, who had been drowned by Máel Sechnaill in 851.[83] Another possibility is that the Cináed in question is Cináed mac Ailpín (i.e. Kenneth MacAlpin, which would make Amlaíb a brother-in-law of his killer Constantine I, a son of Kenneth).[84] Two sons are noted by the annals: Oistin and Carlus, each of whom is mentioned a single time.[85] Both died violently; Carlus died in 868 fighting against Áed Findliath and Oistin was "deceitfullly killed by Albann" in 875.[86]
