Iceland and The Faroes
It is recorded in the Landnamabok that there were papar or culdees in Iceland before the Norse, and this appears to tie in with comments of Dicuil. However, whether or not this is true, the settlement of Iceland and the Faroe islands by the Norse would have included many Norse–Gaels, as well as slaves, servants and wives. They were called "Vestmen", and the name is retained in Vestmanna in the Faroes, and the Vestmannaeyjar off the Icelandic mainland, where it is said that Irish slaves escaped to. ("Vestman" may have referred to the lands and islands "west" of mainland Scandinavia.)
A number of Icelandic personal names are of Gaelic origin, e.g. Njáll Þorgeirsson of Njáls saga had a forename of Gaelic origin - Niall. Patreksfjörður, an Icelandic village also contains the name Padraig. A number of placenames named after the papar, Irish monks, exist on Iceland and the Faroes.
According to some circumstantial evidence, Grímur Kamban, seen as the founder of the Norse Faroes, may have been a Norse Gael.
According to the Faereyinga Saga... the first settler in the Faroe Islands was a man named Grímur Kamban - Hann bygdi fyrstr Færeyar, it may have been the land taking of Grímur and his followers that cauysed the anchorites to leave... the nickname Kamban is probably Gaelic and one interpretation is that the word refers to some physical handicap (the first part of the name originating in the Old Gaelic camb crooked, as in Campbell Caimbeul Crooked-Mouth and Cameron Camshron Crooked Nose), another that it may point to his prowess as a sportsman (presumably of camóige / camaige hurley - where the initial syllable also comes from camb). Probably he came as a young man to the Faroe Islands by way of Viking Ireland, and local tradition has it that he settled at Funningur in Eysturoy.Read more about this topic: Norse-Gaels
