I read that red hair originates in Scandanavia, and not in Britain. That before the Viking conquests of Britain and Ireland in the 8th-10th centuries those islands were populated mainly by dark-haired people. The Vikings mated with the indigenous women of Britain and Ireland (and other lands they conquered), and so that's why we find red heads in Britain and Ireland today. Is this true?

This question appears to be off-topic. The users who voted to close gave this specific reason:
