> I noticed that some European place names have doublets in Siberia and the Far East. After expanding the search area beyond the Urals, it turned out that this is not an accident, but a certain regularity. Discovered new Anglo-Saxon place names stretched as a narrow strip from the Urals to Lake Baikal
Just clicked on random points on his map, he clearly ignoring more obvious explanation for place names. Especially considering that many villages beyond the Urals were founded after Russian colonization, in 15-17th century or such, and were named just like "old" places in European part.
