No, not a single one of them. They WERE Norse. None of them were Lapps. Not a single one.
Your Lapp obsession makes you see things that are not there. Get help.
It's a racial difference ~ not cultural ~ and after several centuries of the Norse perventing native Sa'ami from living on their own land simply because they didn't learn a Sa'ami language, we can now test your DNA and find your Sa'ami lineage.
About half the modern Norwegians on the West coast are, in fact, dispossesed Sa'ami, not Southern Europeans at all.
So, no, it's not an obsession ~ for me it's another topic to study in family history.
