There is no (i.e. < 1% DNA relationship) between the Khazar's and Ashkenazi Jews.
Sorry, but DNA testing has completely disproven what you posted above.
Ashkenaz have an over 90+% direct DNA relationship to the 12 tribes and an almost 95% DNA relationship to the Sephardim.
I.e. you're posting old, old info that has been scientifically disproven.
The word "Ashkenaz" is the Hebrew word for German, Norse or "northmen" and means nothing more than that.
