This is my father's Y-DNA haplogroup, but nowhere can I find any discussion on the ancient origins of this subclade. I understand that the Altai region of Russia is one of the ancient locations, but after that? Did this subclade move in large part into Scandinavia?
The surname is London - very generic with no clues. I am wondering how in the ancient past my ancestors arrived in Great Britain. The scanty clues seem to point to a Viking origin in the 7th and 8th centuries.
Can anyone help shed light on this for me? Any assistance much appreciated.
