I never heard of philsters before (philistines?), and I would not say I am any more an expert than you or Turnoi. But thank you.

Yes, it is indeed true that there must have been some mixing, from one side or the other. I met a person or two from Jordan, the arab country, and one could have passed for a farmer in Suffolk, and the other an Italian or Greek. I dare say even the arabs look down on each other, based on skin tone and so on?
