your grandmother has some... hmmm... trouble with pre-war Poland.
And from perspective of Soviet Union authorities she was some kind of "good guy",
yeah... i got this feeling after reading KPP's history on wikipedia.
But, also, remember that your grandmother could exaggerate her deeds, just to get the passport to Poland.
I don't know what she did to deserve this "title"... lets hope that a 17yo going to the USSR was "revolutionary" enough. :-)
But i'm trying to get the file about her... if only the "Archiwum Akt Nowych" answered my e-mails...
