Re: Holocaust victims in Poland #records
The important question is what locality in Poland? The amount of information differs from place to place.
Search the USHMM Holocaust Survivors and Victims Names List database https://www.ushmm.org/online/hsv/source_advance_search.php and the USHMM Collections Search catalog https://collections.ushmm.org by place name for possible sources of information.
