Vestmenn Vestmenn ("Westmen" in English) was the Old Norse word for the Gaels of Ireland and Britain, especially Ireland. Vestmannaeyjar in Iceland and Vestmanna in the Faroe Islands take their names from it. The Norse who settled in Ireland and Scotland, known now as the "Norse–Gaels", called themselves "Austmenn" "Eastmen", i.e. people who had come from the East (Scandinavia).
