I have created a map displaying the frequency of haplogroup Q in Europe. The data is sparse as Q is most frequent in undersampled countries (Scandinavia and Eastern Europe), so I expect the map to evolve in the future. But it gives a pretty good idea.
There are two kinds of Q in Europe:
1) the Middle-Eastern variant, found mostly in the Levant, Eastern Anatolia and Iran. Note the hotspots in South Sardinia, South Sicily and the Lasithi plateau in Crete, all presumably of Phoenician origin (same for South Portugal and West Andalusia).
2) the Northern and Eastern European variant, which I strongly believe to be of Hunnic origin, since Q isn't found in western Siberia, and its distribution matches almost perfectly the borders of Hunnic Empire. Note that the Goths from Sweden were vassals of the Huns. All the regions associated with the Goths (Sweden, Poland and the north shore of the Black Sea) have a relatively high percentage of Q (let's not forget that the Huns were a ruling minority). Norwegian and Swedish Vikings spread hg Q to Iceland, Britain, and Russia (notably the region north of Moscow, which is also a hotspot for haplogroups I1 and I2b, and an early Varangian settlement in Russia).
One mystery is the presence of Q among the Basques.
