I think the people of Transcaucasia are the khazars Jews don't fit the description
http://www.apfn.org/THEWINDS/library/khazars.html More with above link This peculiar and obscure race inhabiting that land were described as blue-eyed and of very fair complexion. Commonly they had long reddish hair and were reported as very large of stature and fierce of countenance. 11 Other sources have added observations that there were "Black Khazars" and "White Khazars," noting that the latter were "light-skinned and handsome, while the former were dark-skinned." This has, however, been rather conclusively refuted by scholars who have established that the distinction was not racial but social. The "Black" or "Kara" Khazars constituted the lower strata or caste, while the "White" or "Ak" Khazars were of the noble or royal classes. This type of class distinction was fairly common in Eastern Europe as evidenced by the more commonly known terms "Black Russian" and "White Russian," denoting not skin color but class. 12
In his book An Introduction to the History of the Turkic Peoples, Peter Golden claims that the Chinese T'and-shu chronicle describes the Khazars, generally, as "...tall, with red-hair, ruddy-faced and blue-eyed. Black hair is considered a bad omen." 13
THE KHAZARS OF CONQUEST AND WAR
Of the ferocity and warlike tendencies of the Khazars there is little doubt and much historical evidence, all of it pointing to a race of people so violent in their dealings with their fellow men that they were feared and abhorred above all peoples in that region of the world.
The Arab chronicler Ibn-Said al-Maghribi writes, "they are to the north of the inhabited earth towards the 7th clime, having over their heads the constellation of the Plough. Their land is cold and wet. Accordingly their complexions are white, their eyes blue, their hair flowing and predominantly reddish, their bodies large and their natures cold. Their general aspect is wild." 14
The ninth-century monk Druthmar of Aquitaine, in his commentary on Matthew 24:14 in Expositio in Matthaeum Evangelistam, stated that the Gazari, or Khazars, dwelt "in the lands of Gog and Magog." 15
Legends and stories abound, some of which are true according to the above quoted Aquitaine monk, that center around Alexander the Great and his attempt to enclose the Khazars and quarantine them, due to their violent and barbaric nature, from the rest of the civilized world. This endeavor apparently failed, Druthmar claimed, and they escaped. Some legends even claim they were cannibals. 16
