There is however a long history of relatively friendly (for the region) contacts with middle east cultures and there was a turkic minority in Poland until sometime in the late 19th century (their descendents are still around, they just don't speak a turkic language anymore).
The Thirteenth Tribe book has been proven to be incorrect; Ashkenazi Jews are not turkic but are in fact descended form the Semite Jews in Germany since the Middle Ages and before and the genetic evidence for this exists.
The Hun. word is 'ostor' and I believe it is a turkic or Alanic loanword.
It got changed to choinak--a combination of the local word for tea, and a much more pleasant to the turkic ear version of "nik."
