School #20A
WYM 6.11.41 to SIEGFRIED 9 24
When I searched Szmul Przenica I got 2 results with the same complete name "SZMUL LUZER PRZENICA". Both results were born in 1931 with no exact date, but this does fit with School #20A in terms of year. Each listing had incomplete addresses but with the infromation avalible in each listing I was able to get three addresses for Szmul Przenica. I am confident that this confirms the identity.
I was able to connect Udla Przenica as Szmul Przenica's mother because she is about 30 years older than him, female, and they lived at all the same addresses as well as date moved. I was able to connect each sibbling by the exact same process.
As I was browsing the Labor Cards, one of them was very faded and almost nothing could be read from it, I was able to make out two letter on the first name as "Sz". I cannot in any way confirm that it is Szmul Przencia but I believe there is a possibility because of the uncommon placement of "Sz" in first names.
