I have reached out to apgda(@)gdansk.ap.gov.pl and – sekretariat_ap(@)bialystok.ap.gov.pl to try to obtain information about my deceased grandfather Mr. Boris Tennenbaum, born May 15, 1903 in Białystok. He was born in Białystok and I would like a birth certificate, registration and residential documents for the period between May 15th 1903 and December 10th 1926. I also sent them my name and address. I don’t suppose anyone could help me or give me some suggestions on how to get information about Boris? The attached contains Boris Tennenbaum’s 1903 Białystok birth record, not certified. It is the last record on this page. As far as I know, he was born in Russia. Without knowing where he resided in and around 1917-1920, when Białystok became part of the newly reconstituted Polska, there is no way to know whether he was a citizen of Polska or Russia. Many thanks in advance.
