On the other hand, the fact that king lists locate Dub's demise to Forres might indicate that Clann Custantín meic Cináeda was instead based in the north. Moreover, the fact that the Prophecy of Berchán records that Custantín mac Áeda retired to St Andrews, a site where his descendants, Illulb and Cuilén, are also said to have been buried, coupled with the location of Cuilén's death in the south against the Cumbrians, could reveal that Clann Áeda meic Cináeda was centred south of the Mounth. Such a location may also be evidenced by the aforesaid deaths of the Abbot of Dunkeld and the satrap of Atholl, men who seem to have fallen supporting the cause of Cuilén against Dub.
