During the three years that followed this plundering of the monastery, we find Dunnchadh Ua Robhacain coärb of Columcille and Adamnan, which implies that he was abbot of Raphoe; but, on his death in 989, we find that Dubdahthe, the abbot of Armagh, takes the coärbship of Columcille by the advice of the men of Erinn and Alban.[640] The monastery of Iona, however, appears soon after in an efficient state, as we find it governed by a local abbot whose death is recorded in 1005.[641] In the same year Malcolm the Second commenced his thirty years’ reign over Alban, now for the first time called Scotia. He is said, in a chronicle of the twelfth century, after the great battle of Carham in 1018, ‘to have on that day distributed many oblations to the churches as well as to the clergy.’[642] In Iona he appears for the time to have restored to the abbot the title of coärb of Columcille, for we find that in 1007 ‘Muredach mac Crican resigns the coärbship of Columcille for God’—that is, becomes a recluse; and Ferdomnach is elected to the coärbship by the advice of the men of Erinn at the fair of Taillten,[643] which implies that his coärbship was limited to Ireland; and we find that he was in fact abbot of Kells, as was his successor; while, on the other hand, the death of Flannobra, coärb of Iona, is recorded in 1025.[644] In the following year Maelruanaidh Ua Maeldoraigh, lord of Cinel Conall, that is, of the tribe of Conall Gulban, went over the sea on his pilgrimage.[645] The expression ‘over the sea’ implies that he went to Iona. [Sidenote: A.D. 1025-1028. Alwynun bishop of Alban.] Cellach, the bishop of Alban, is said to have filled that office for twenty-five years, which brings his death towards the end of the tenth century. The first bishop to whom we can assign a fixed date after that is Alwynus, who is said to have been bishop three years, and whose death must have taken place in 1028, which places his election as bishop in the year 1025. Between Cellach and Alwyn we have two names given us by Bower and Wyntoun, those of Malmore and Malisius; but we know nothing beyond their names. During the tenure of one or other of them, the district of Lothian was ceded to Malcolm the Second by Eadulf Cudel after the battle of Carham in 1018, and the churches of Lothian naturally fell under the superintendence of the bishop of St. Andrews as sole bishop in Scotland. But not the least important event connected with Malcolm the Second was that he gave his eldest daughter in marriage to Crinan, lay abbot of Dunkeld, and by this marriage the hereditary lay abbots of Dunkeld gave to the Scottish throne a dynasty of kings who were destined to extinguish that ancient church, with its peculiar institutions, from which their ancestors had emerged.
