After Michael's death in 1203, a certain Koli is recorded to have been consecrated in 1210. The situation between this span of years is uncertain. On one hand, it is possible that the see was vacant between these years. On the other hand, Koli could have been elected bishop in 1203, but only consecrated in 1210. Another possibility is that the see was administered from Lismore—the future seat of the Diocese of Argyll—under the ultimate authority of Áengus, the aforementioned Meic Somairle dynast slain in 1210.
