The Farfarers: Before the Norse (2000) is a book by Farley Mowat that sets out a theory about pre-Columbian trans-oceanic contact. Mowat's thesis is that even before the Vikings, North America was discovered and settled by Europeans originating from Orkney who reached Canada after a generation-spanning migration that used Iceland and Greenland as 'stepping stones'. Mowat's ideas are controversial and have been accused of being over-speculative. The book has been published in the UK as The Alban Quest. - Source: Wikipedia
