I consider some Jewish groups as very strange, like Ethiopian Jews who are Black, Bukharian Jews from Uzebekistan, there are even Jews in India and China. All of them have settled Israel and live there now. I don't know how these groups were created and whether they are related to other Jews (Ashkenazi and Sephardi). I guess they are not.
There are also fake Jews in Israel who are actually Russians or Ukrainians.
