Ashkenazi is about 45%. Then there’s the Sephardi, also not Levantines. Nor are the Maghrebi, Beta or Kaifeng. The Mizrahi at least have a bit of Levantine in them.
Palestinians are Levantines, not Arabs per se. Well documented! Their ancestry is a mixed bag of well integrated people. A bit Arab, Hamite, Turanid, Persian and S European. In fact today’s Palestinians and Lebanese are up to a 95% match for the same mix. Presumably your “worldly” experience makes them Bolivians?
