I don’t know any Polish people with red hair. And I’m a quarter Polish.
Doesn’t matter though.
I am of Polish and Irish extraction, and have inherited red hair from both sides of the family. I don’t know which paternal ancestor had it, but my aunt is a redhead. On Mom’s side, my Polish Grandpa was also a blue-eyed redhead.
Several of Grandpa’s progeny (myself, my brother, and a bunch of cousins) also have red hair, though not carrot-red; our hair is more auburn.

The problem arose when the noble classes were reconstituted and numerous French and British nobles took jobs there. Plus, thanks to several well-known British monarchs that red hair has been spread into "The Family".
The original Slavic population probably has a lower incidence of redheads.

You GOT to be kidding.
Regardless, Columbus is truly a mystery man. If he’s not Italian, my guess is he was a Sephardic Jew and assumed his Italian identity as he knew Isabella was an anti-Semite.
I do know at least one with red hair. (I’m 1/2 Polish) The redhead is still alive...and his nickname (forever) has been Rusty.
