In the early 1190s, the "Chronicle of Mann" reveals that Cristinus, Bishop of the Isles, an Argyllman who was probably a Meic Somairle candidate, was deposed and replaced by Michael, a Manxman who appears to have been backed by Rǫgnvaldr. The tenure of Cristinus seems to have spanned at least two decades during a sustained period of Meic Somairle power in the Isles. His downfall, however, came about at the time of the Crovan dynasty's resurgence under the then-recently enthroned Rǫgnvaldr.
