I think most redheads, like myself, are of Irish, English and Scot descent. However, my daughter in law, who is 100% Lebanese, has dark red hair, with fair skin. And that is not uncommon for people from that area, including Jews. I think the main difference is red heads like I am, have blue eyes, while those of middle eastern descent have brown eyes. The really rare ones have green eyes; I don’t know where they come from.
I’m 100% scotts/irish and have (had) red hair and brown eyes. My grandson has red hair and blue eyes, his grandparents are me, my italian brunette wife, a mestizo indian and anglo blonde
Scottish, here. You’d never know it unless I grew a mustache, especially considering that I’m about 3/4 Italian (with blue eyes as well).
