Just found this now, thank you for putting it together! I’d never thought about this before.
In case anyone else is curious I dug into Polish citizenship by descent. It looks like the main requirements are (a) someone in your family had citizenship after 1920, (b) the chain of citizenship isn’t broken, i.e. you can’t become a citizen if neither of your parents are, and they can’t become a citizen if neither of their parents are, etc. and (c) no one in that chain was adopted, involved in the military (including signing up for the draft), in a publicly funded job (including teaching), plus maybe a few more exceptions.
