In Scotland, Culdees were more numerous than in Ireland: thirteen monastic establishments were peopled by them, eight in connection with cathedrals. The Ionan monks had been expelled by the Pictish king Nechtan son of Derile in 717. There is no mention of any Culdees at any Columban monastery, either in Ireland or in Scotland, until long after Columba's time: in 1164 that Culdees are mentioned as being in Iona but in a subordinate position. The Culdee of Loch Leven lived on St Serf's Inch, which had been given them by a Pictish prince, Brude, about 700. In 1093 they surrendered their island to the bishop of St Andrews in return for perpetual food and clothing but Robert, the bishop in 1144, handed over all their vestments, books, and other property, with the island, to the newly founded Canons Regular, in which the Culdees were likely incorporated.
