Viking Age Gotland was Baltic, Baltic-Finnic

Following PCA shows strong evidence about the Viking Age Gotland and shows also that, despite of the eastern Swedish influence, the Gotland was an exception and mostly settled by Baltic and Baltic Finnic people. It looks like the Swedish Vikings made raids to Estonia/Saaremaa and founded a settlement to Ladoga, but in Gotland there was a persisting Baltic or Baltic Finnic settlement. I added ancient and Asian samples to correct the stretching error, which is not corrected completely by the parameter "autoshrink" in SmartPCA. Autoshrink tries to avoid stretching of edge population. Because modern Europeans are a mixture of ancient hunter-gatherers, farmer and steppe populations, using those groups stabilizes the modern picture and makes the European PCA "orthodox", i.e. puts the Finns to right position (a hint to those scientists who are not aware of this error). PCA's, the first including all modern samples plus balancing ancient samples and the second a close-up (some other than Gutnish Viking samples can be of low quality and the location affected by this fact) (the close-up updated due to sample relatives) :
