It's actually difficult to tell via a place, instead you have to use DNA and culture. Hell, some of the very same peoples have been called by different names depending on who they were trading/warring with. Scythians, Gemanians(many tribes called by one tribe's name), Goths, Vikings, Celtics, and many, many others are/can be considered Aryan. They moved around *a lot* via ships and such for trade and conquest. The people's who encountered them considered them just and lawful, merciful to their conquered, very tall, blonde and/or red haired, incredibly muscular(the men) or incredibly beautiful(the women *and* men).
