Really? This doesn't make sense linguistically, but that doesn't mean as much. What sources do you have for this?
I'll leave Viking influence on England to other people (not my specialty). If you read the rest of the thread it is discussed, even linguistically by The Augusta and by sonic.
Linguistically, Viking influence in Scandanavia is very obvious .
As far as the Viking creation of Russia goes (this is one of my specialities), Russia was founded by a Sweedish tribe, Rus'. They sailed down the Russian rivers and traded with the Byzantines, the Volga Bulgars, and with the Moslems. The main source would be the Russian Primary Chronicle (Povest Vremenik Let). Linguistically, Old Norse and Russian are very different, but keep in mind that over the past thousand years or so the Russians have had many influences: Byzantine Greeks, Tatars, Turkic tribes, Poles, Lithuanians, Germans, French, so on and so forth.
Beside the RPC, the best source I can point you towards is The Varangians of Byzantium by Sigfus Blondal.
