I looked through the Labor Cards for Machtynger and they began at Macznik, so I am unsure where Machtynger would fit into that. I looked through but could not find her. I also searched through the lower L’s, but could not find her. I did a Google search and searched Miriam by both names and her address. I found the name Mariam Dworja several times, but she always had different last names Then, I searched Mirjano Dworja Machtynger, a name she is also listed under, and found her old address AND a new address, as well as an occupation! Her occupation was a student and she moved Polnoca 5.
There was no date given with the change of address. I Google searched the address and also Mirjano by different spellings. I was unable to find any information. I have to assume that she was taken in one of the deportations to Chelmno or another Death Camp, because of her young age she probably would have have been transfered to a labor camp.
