There were 2 Fajga Wajnsztajns that appeared when I searched for her, but I believe that they are both the same person, given that their birth dates and ghetto addresses were the same. Fajga's first address is listed to be Mittel 53, and her second address is listed as Sophien 9 5. The other source for Fajga also lists another address: Tal 14 7. Fajga was a schuelerin (student) at School #10B.
According to the records of Fajga's father, the Wajnsztajns changed addresses on November 21, 1943 to Talweg 14. I located Fajga's parents because they had the same address and address change as Fajga did, and were born in 1905 and 1910.
