Segine’s own death followed a year after. His successor was Suibhne, of whom we know nothing except that his father’s name was Cuirtri, but it is unlikely that at this early stage any one who did not belong to the tribe of the patron saint could be elected an abbot, and the only notice we have of him is his death after having been five years in the abbacy.[322] [Sidenote: A.D. 657-669. Cummene Ailbhe, son of Ernan.] He was succeeded in the abbacy by Cummene Ailbhe, the nephew of his predecessor Segene, whose tenure of office was signalised by equally important events. His first year is coincident with the extension of the dominion of Osuiu, the Northumbrian king, over the Britons of Strathclyde, the southern Picts and the Scots of Dalriada; but, though the latter ceased for a time to possess an independent king, the rule of Northumbria could not have affected the church to which her own church was affiliated. Accordingly, when Finan, the successor of Aidan, died, we find that Colman was also ‘sent out of Scotia,’ and succeeded him as bishop.[323] Tighernac records, in the same year, the death of Bishop Finan and of Daniel, bishop of _Cinngaradh_ or Kingarth, in Bute; and in the following year, a visit of Abbot Cummene to Ireland;[324] and, as Bede says of Finan that he was ordained and sent by the Scots, while, in the case of Colman, he uses the expression that he was sent out of Scotia, or Ireland, this rather confirms our suspicion that the bishops called in to consecrate these Northumbrian missionaries were the bishops of Kingarth, and that the death of Bishop Daniel in the same year rendered an appeal to Ireland necessary.
