Editing Olaf Guthfrithson (section)

==Family==
Olaf's father is identifiable as Gofraid, who was king of Dublin between 920 and 934, and also briefly ruled Northumbria in 927.<ref name="D29">[[#Downham|Downham (2007)]], p. 29</ref><ref>[[#Hart|Hart (2004)]]</ref> Gofraid was a grandson of [[Ímar]] but no patronymic is given in the original sources. This may be because he was a child of a son of Ímar who never ruled Dublin, or he was a child of a daughter of Ímar, which in either case would mean his legitimacy to rule in the eyes of his contemporaries was dependent on the identity of his grandfather, not his parents.<ref>[[#Downham|Downham (2007)]], p. 33–34</ref> Ímar, possibly identical to [[Ivar the Boneless]], was the founder of the [[Uí Ímair]] and was one of the earliest kings of Dublin in the mid-ninth century.<ref>[[#BartlettJeffrey1997|Bartlett and Jeffrey (1997)]], p. 44</ref>

Three other individuals are identifiable as sons of Gofraid; Albann, Blácaire and Ragnall.<ref name="D29"/> Albann was killed in battle against Muirchertach mac Néill in 926.<ref>[[#Downham|Downham (2007)]], p. 238</ref> Blácaire ruled Dublin from 939 onwards, and [[Ragnall Guthfrithson|Ragnall mac Gofraid]] ruled Northumbria in 943 and 944, probably along with his cousin Olaf Cuaran, until they were driven out by [[Edmund I|Edmund I of England]].<ref name="FOP115"/><ref>[[#Downham|Downham (2007)]], pp. 111–112</ref> [[John of Worcester]], writing in the twelfth century, claimed that Olaf had married a daughter of Constantine II of Scotland prior to 937, but this evidence is considered unreliable.<ref>[[#Downham|Downham (2007)]], p. 150</ref> The thirteenth century chronicler [[Roger of Wendover]] wrote that Olaf married Aldgyth, the daughter of a Northumbrian earl called Orm as a consequence of the agreement at Leicester between Olaf and King Edmund.<ref>[[#HB|Harper-Bill (1998)]], pp. 25–26, n. 166</ref>

An individual named [[Cammán mac Amlaíb]] is identifiable as a son of Olaf. The ''Annals of Ulster'' record he was defeated at a place called Dub in 960. Cammán may have been one of the meic Amlaíb (sons of Olaf) who the ''Annals of the Four Masters'' mention in 962.<ref>[[#AU|Annals of Ulster]], s.a. 960</ref><ref name="D249">[[#Downham|Downham (2007)]], p. 249</ref><ref name="D262">[[#Downham|Downham (2007)]], p. 262</ref><ref name="A4M962">[[#A4M|Annals of the Four Masters]], s.a. 962</ref> According to this account the sons of Olaf and the Ladgmanns (lawmen) came to Ireland and plundered [[Conaille Muirtheimne]] and [[Howth]]. Afterward the lawmen went to Munster to avenge their brother Oin. They continued the plunder there and were defeated by the Irish in [[Uí Liatháin]] where 365 of them died. In the same year an unnamed son of Olaf led a raid from [[Ireland's Eye]] on [[Anglesey]] and Britain.<ref name="A4M962"/><ref name="D262"/> Cammán may be identical to Sitriuc Cam, an individual who in 962 made a naval attack on Uí Cholgain, but was forced to flee back to ships after a force of Dubliners and Leinstermen overtook him and slaughtered some of his men.<ref name="D269">[[#Downham|Downham (2007)]], p. 269</ref> An individual named Gofraid mac Amlaíb recorded by the annals as dying in 963 may have been a son of Olaf or he may have been a son of [[Amlaíb Cuarán|Olaf Cuaran]].<ref>[[#Downham|Downham (2007)]], p. 253</ref> The ''Annals of Clonmacnoise'' list an Ímar, a "son of the king", among the dead at Brunanburh who might be a son of Olaf, although the origin of this list is uncertain.<ref>[[#AClon|Murphy (1896)]], p. 151</ref><ref>[[#Downham|Downham (2007)]], p. 259</ref>
