The "Annals of Clonmacnoise" mention two sons of Sitric, Auisle and Sichfrith, falling at the Battle of Brunanburh in 937. Another son, Aralt, ruled as King of Limerick for an unknown length of time until his death in battle in 940. Sitric's son Amlaíb Cuarán (d. 981) reigned twice each as King of Dublin and King of Northumbria, and may have been the basis of the Middle English romance character Havelok the Dane. Gofraid (d. 951) may have been another son though his father is only named as "Sitric", leaving his relationship to Sitric ua Ímair unclear. "Orkneyinga saga" tells that a daughter of Sitric named Gytha was married to Olaf Tryggvason, King of Norway. According to Hudson, this is unlikely to be correct, since the marriage is said to have occurred sixty-three years after Sitric's death. It is much more likely that Gytha was actually a granddaughter of Sitric through his son Amlaíb Cuarán.
