For the youtuber i can say maybe this Tatars were Coastal Tatars or Caucasian Turkic. Or, that also could be, these were not Tatars just called Tatars because of the conditions and wher they came. My grandpa told me there are a family in Kirsehir which called Cerkez although they are Tatars. The official and people gave them this name because they were refugees from Russia. These tatars could be maybe Caucasians like Circissians, some score up to 10% mongoloid, some not even 3%.
