Something else: Last time I was in Finland, Thule told me (and you were not there) that many Medieval German Swords and graves of Warriors/Noblemen have been found in Finland.   In fact he told me that more such German swords had been found in Finland than Germania Proper and/or Frankreich. Yes, there are known these kind of Merovingian king-swords around 130 pieces all together, and around 80 of them have been found in Finland, when remaining 50 pieces have been found from modern-day France, Belgium, German etc.     Those many dead Germanic warriors burried in Finnland, are the source of this specific word KUNINGATAR I think. There are no evidence of ethnic origin of these graves. Popular theory is that there are local noble men, who may been served as mercenary or in  hird , maybe Byzantiums Imperial varangian guard too, because there have been lot of eastern coinage in these graves too. But what is ethinc background for word 'local' I just used, is a subject to discuss and study. However Finns share ethnicity with other north europeans despite our language differs lot.
