[quote user="funky2004"]She's Russian all right. Probabely her roots are in one of the eastern Russian regions, like Uzbekistan, Tadzhikstan or Kirgizia.[/quote]
Well, all the three are not Russian regions, I'm sorry. [N] They seem to be independent countries, situated to the South of Russia, but they were really republics of the USSR in the past.
As for the girl, you're right, her roots may be in Tadzhikistan because of her not European eyes and mulatto skin (unlikely in Uzbekistan and sure not in Kirgizia).
Another version: one of her parents (or even both) can be from Tatarstan, it's a region of ethnic minority in the European part of Russia (Kazan is the region's administrative center). I rather think she's Tatarian at least by half.
