Every member of my family has blue or green eyes, half of us have brown or blond hair, and every man is 6'0 (tallest living is 6'7). On the streets of St Petersburg or anywhere in the west Russian countryside, the people look the same, and I have actually met people from there.

The original "Aryan" language was literally Pre-proto-Balto-Slavic (AKA Sintashta and its forest steppe predecessors). The Germanic vocabulary split off relatively early and diverged into unique forms. In Old English there were more aryan cognates than now. The spread of the Germanics came from Sweden and Denmark primarily, and even in the Nordic bronze age there were Slavic settlers that adopted Germanic culture. Prior to the current era, central Europe was mostly populated by Celtic/Italic speakers (La Tene and Hallstatt Celts), they then later adopted Germanic.

Here's a hastily put together map of the more recent spread of the Teutish tongues throughout Europe. The most widespread were the North Teuts (Goths/Swetheod most of all), followed by the Franks and the Angeln/Danes. The most important thing to note is that every one of these groups spoke low Teutish (Charles the Great spoke a kind of Low Franconian, before or around the evolution into middle and high Germanic) and the ursaxon tongue was also a low Teutish tongue akin to English, Frisian, Low Frankish. Old Frisian and English were closer to north Germanic than any other "west" Germanic tongue, for all intents and purposes it is still easier to read, speak, and understand Danish over High German. Burgundians were related to the Bornholmers.
