I would rather say northeastern/southwestern. Northeastern: the Danelaw up North to the Scottish highlands, Southwestern: all the rest of England including Cornwall + Wales
But people have moved since the Viking ages, they must have some celtic blood, like Welsh actress Catherine Zeta-Jones or the Scotsman with an Irish name Sean Connery.
Many Normans were also certainly brown-haired because mixed with autochtonous Neustrians.
Vikings settled down in the Shetland and the Orkney Islands. They printed a strong mark there. All the people from these islands could pass as Norwegians.
There are many Dinarids/dinaricized types and Alpines among Austrians/Germans and you can find a good number of Bulgarians belonging to Northern phenotypes, so majority of Austrians and Germans could fit here (even though phenotypical proportions are quite different, especially in comparison to Northern Germans).
On the other hand, the vast majority of Brits (70%+) cannot pass as Bulgarian.
I suppose Spanish and Greeks.
Look here on this pca, Sardinians cluster near Canarians. I know you are part Iberian, so you'd probably cluster between Sards and IBS, but not far from Canarians. Probably where Skoglund farmer is located on this pca.
