Dear Ms. Worthington,
Thank you for posting your request on History Hub!
The Auschwitz-Birkenau Memorial and Museum has an online database of prisoners that may be useful for your research. The Arolsen Archives International Center on Nazi Persecution also provides Research for names of Auschwitz prisoners on their website. Plus, you may be interested in the U.S. Holocaust Memorial Museum’s Resources on Survivors and Victims. We suggest that you contact these organizations for additional assistance.
In addition, the FamilySearch research wiki for Poland Genealogy has information about Polish birth and death records. Lastly, we suggest that you contact the National Digital Archives of Poland, ul. Hankiewicza 1, 02-103 Warszawa, Poland. The email address is email@example.com.
We hope this is helpful. Best of luck with your family research!
