100% Western European.
Yup. I am whiter than white. Whiiiiiiite. Super Celtic. Practically Neanderthal. How disappointing. I wanted to be American Indian!
Scandinavia (Sweden, Norway, Denmark, though also found in Great Britain, France, Germany, Netherlands, Belgium, the Baltic States, Finland): 22%
Europe West (Belgium, France, Germany, Netherlands, Switzerland, Luxembourg, Liechtenstein): 18%
Great Britain (England): 16%
Iberian Peninsula (Spain & Portugal): 1%
The Celts were early, dominate tribes of what is now Ireland/Scotland and North Western Europe, including the Iberian Peninsula. So, that’s my dominate ancestry, though I've got quite a lot of Germanic / Teutonic stuff going on as well.
The Italy/Greece thing is a stunner. That particular gene line is also found in France, Switzerland, Portugal, Spain, Serbia, Hungary, Bulgaria, Austria, Croatia, Bosnia, Romania, Turkey, Slovenia, Algeria, Tunisia, Montenegro, Albania, Macedonia, Kosovo. No way to know what tribe I'm related to: Achaean/Arcadian, Dorian, Aeolian and/or Ionian. I guess a couple of our ancestors moved from one of these countries and married up with other ancestors in France or the Iberian peninsula way back long long before Columbus sailed the Ocean blue.
So, fetch me my kilt and my bagpipes.
