10% Iberian Peninsula was surprisingly in my first result, then a revision eliminated that and a couple other small percentages. The revised one is more what I expected, Great Britain, Ireland, etc., Northwestern Europe and Norway.
I suspect it’s the Celtic that creates the mismatch. Mine originally claimed I was 25% Irish. Now Spanish has increased to 60 percent and 10 percent Portugese. Celts inhabited the Portugal area and parts of Spain.
