More likely that those migrations were multi-generational: the clan moved 20-50 miles every season following the game, and the descendants eventually got to a different continent. However, there are examples of somewhat shorter distances in more modern times: I find it fascinating how the different cultures of Europe moved about: the Scandinavians to England and Normandy, later the Normans to Spain, Sicily, and Africa, the Slavs to the Balkans and Adriatic, etc. These are perhaps 1000 miles at most, but it seems like an entire warrior class and parts of the population went far away, conquered and installed themselves for generations in a foreign (and fully populated) place.
