One of the other named kings was Cináed. Considering the fact that the "Anglo-Saxon Chronicle" numbers the kings at six, if Cináed was indeed present, it is unlikely that his rival, Cuilén's brother Amlaíb mac Illuilb, was also in attendance. Although the chronology concerning the reigns of Cináed and Amlaíb mac Illuilb is uncertain—with Amlaíb mac Illuilb perhaps reigning from 971/976–977 and Cináed from 971/977–995—the part played by the King of Alba at the assembly could well have concerned the frontier of his realm. One of the other named kings seems to have been Maccus mac Arailt, whilst another could have been this man's brother, Gofraid. These two Islesmen may have been regarded as threats by the Scots and Cumbrians. Maccus and Gofraid are recorded to have devastated Anglesey at the beginning of the decade, which could indicate that Edgar's assembly was undertaken as a means to counter the menace posed by these energetic insular Scandinavians. In fact, there is evidence to suggest that, as a consequence of the assembly at Chester, the brothers may have turned their attention from the British mainland westwards towards Ireland.
