Sa'ami meaning Laplanders?
You do realize that in Roman times it was necessary for most of the coastal populations along the Baltic to evacuate the area due to a stretch of really bad climate change ~ they relocated to Freisland in what is now Nederland. All of those islands were much larger at the time ~ but that's where the ANGLES originate ~ the really blond haired crowd. Through time as the climate changed to the better they rowed their tiny boats back across the Baltic to Southern Scandinavia.
Through that period whatever Sa'ami had lived in the South (they had been met by the Greeks BTW) withdrew further North to the Arctic where it was apparently nicer ~ lots of game, reindeer ~ etc. More like the Norwegian coast is today up in the North.
At the moment only Finland's Sa'ami use the term Lapland ~ and I don't believe they're the folks who passed on clinker building tech to the Norse. That'd be more likely the Northern Sa'ami.
