The most famous figure in the list after Roderc is Eugein map Beli, who is no doubt intended to be Ohan (AT) or Hoan (AU) a king of the Britons who slew Domnall Brecc in an ambush in Strathcarron in 642. This battle is the subject of an awdl in the "Y Gododdin" collection, but in the poem the victor is not named, only said to be a grandson of Neithon (according to an emended reading of the surviving versions of the text). The poem describes this surprise attack as being launched from a fort above Strathcarron, and it seems likely that Dumyat is intended, a hillfort associated with the Maeatae, who had been attacked a generation earlier by Domnall Brecc's formidable grandfather, Áedán mac Gabráin. It seems likely, therefore, that Ohan/Hoan was a king of the Stirlingshire Britons, and that his action avenged the earlier attack by Áedán. There is no reason to associate Ohan with Alclut, but the genealogist probably felt there was no harm in inserting such a prestigious character, and his grandfather, into the genealogy, particularly if there was a substantial gap to fill between Roderc and Guret, and he may possibly have been the father of Domnall (although the name Ohan/Hoan/Auin/Eugein is very common). It may well be that Ohan's action led to a decline in the power of the Cenél nGabráin and subsequent reoccupation of Dunbartonshire by the British under Gureit. (see now Fraser 2008)
