Thank you,I'm certainly interested in peaceline in Poland in connection with the events in my region
Maybe try to contact one of the Polish consulates in Ukraine to find out something.
Here are phone numbers and e-mail addresses:
luck.msz.gov.pl/pl/konsulat/ambasada_i_konsulaty_rp_na_ukrainie
Looks like for Donieck district one should contact consulate in Kharkiv:
charkow.msz.gov.pl/pl/konsulat/kontakt/kontakt1;jsessionid=7330754DD3A8B5E61C09596B7DD5FFC9.cmsap2p
there is evidence only photo of my grandfather Porfiria
I don't know much about those things but I suspect you would need more than a photo - probably some kind of documents, like birth certificate of your grandfather or at least his adoption papers (if there were any at all being issued during the revolution). It probably would be also good to find out where his father Nicholas ("Mikołaj" in Polish) or his mother was born in Poland, so you would have some kind of document connected to his biological parents, like birth certificate or baptism certificate or marriage certificate, I suspect.
Btw, how did you find out about your family history if the only thing you have is your grandfather's photo?
Do you have any old family letters or something?
Btw, maybe you could find some useful information on this forum (it's in Russian):
