I have a book about a Native American who runs away from her tribe and survives the cold winter in Nova Scotia, where she meets up with Inuits. They all, in turn, meet up with the Viks and eventually this gal has children and dies in Greenland.
Plausible. The path would work. I read it every so often, just because it is so interesting.
(Forgot the name of it, though...)
Sounds good.
