If Wyntoun's account adds little to earlier ones, at the end of the 16th century George Buchanan in his "Rerum Scoticarum Historia" added much, generally following John of Fordun. In this version, the Scots had been expelled from Scotland when the Romans under one Maximus conquered all of Britain. His father Eugenius had been killed by the Romans, and Fergus, Fergusius II according to Buchanan's count, was raised in exile in Scandinavia. He later fought with the Franks, before eventually returning to Scotland and reconquering the Scottish lands. He was killed in battle against Durstus, king of the Picts, and was succeeded by his son Eugenius. A linked tradition traces the origin of Clan Cameron to the son of the royal family of Denmark who assisted Fergus II in the above restoration to Scotland.
