Hi Gerhard, thank you for the answer. According to the information from my family in Brazil, they arrived in 1926, when Jadwiga was less than one year old and she was born in 1925.
Is it likely that they have gone to Warsaw to process a passport? In that case I would have to send an email to the archive, I was also reading that it was very common for Poles to leave through the port of Amsterdam, but I haven't found anything yet.

On the other hand, do you know where I could get information on Volhynia? In order to access Polish citizenship I need to prove that my great-grandparents were established residents but I don't know how to prove it, I found a document from Ludwig Werner, brother of Gottfried Werner (1896) who was resettled in 1940 and there it appears that he was a Polish citizen. Thank you for the help, greetings.
