I am not sure if they ever renounced their Polish citizenships (or, indeed, if the present-day Polish authorities would ever have this on record).
If my mother were able to locate their birth certificates in Poland knowing their places and dates of birth, would she be entitled to apply for Polish citizenship? What sorts of information would be required of her to do this?
It should be possible, but I'm not sure what documents are needed.
For my brother which both my parents are polish citizens, we needed a polish birth certificate and a bunch of forms filled out. I would call up the consulate in chicago or embassy in DC (or a consulate in europe) and schedule a meeting and find out what is exactly required.
