Hello again,
your grandfather's parents names were Marian Drozdowski and Maria Drozdowska (maiden name Filiczkowska). After the second world war they didn't come back to Poland from Germany they went to America instead and they were living in Chicago. They travelled there with their youngest daughter Maria and her husband Henryk Kanabus. They had four kids together, the oldest one was named Theresa, the second one was Krystyna, than Barbara and the youngest was a boy named Henry. The pictures you posted is of this family back when they were children with thier grandparents. Last year I started looking for thier family and I found Krystyna. Krystyna currently lives in Tuscany Arizona and has three daughters. Theresa passed away in 2002 and Barbara passed away in 2008. After the war Helena and her husband Franciszek Wos with their kids Zygmunt, Kazimiera and Danuta went back to Poland. They were living in the city of Wroclaw. They had two more kids there Irena and Anthony. Zygmunt is my father. They all still live in Wroclaw. Antonina, your grandfather's sister, went back to Poland with her husband Burzynski and thier two daughters Krystyna and Danuta. They lived in the city of Koszalin. I don't know much about them because I never met them. The oldest Kazimierz Drozdowski and his wife Zofia they also lived in Poland but I don't have much information about them either. All I know is that they had a kid name Marian who was born in 1940. Before the war the family was living in Malynsk wolyn, Poland. During the second war most of the family was shipped off to Siberia by Russians. The rest of the family (which is your grandfathers parents) and thier kids in 1943 escaped to Germany to escape the genocide of the Ukrainians. If you want to know more about the history of the land you have to look for "Wolyn naszych przodkow". I would love to have more pictures of your family if you could send some more I would greatly appreciate it. I look forward to hearing from you and I hope I was able to answer some of the questions you may have been searching for about your ancestors. Please let me know if there is anything else that you would like to know and I will gladly try to help.
