ר' יצחק הכהן -כץ (כץ), אב"ד ניקלשבורג - DNA test

Is there anyone here who is definitely a descendant of his son after son, and did a DNA test?

Naftali Vokstein is looking for someone who knows for sure that he is his descendant son after son in order to compare with the DNA test. which i did ,and see if the Wartski Hchoen family is his descendant (son after son).
Thank you all
