I found first Dorka Zysman born 28/09/1921 and she lived at Goldschm 18 flat 1 and she had a ghetto note of Lanziger 15 UMG 3.9.42 Brot.
I ran another search and found Dortea Mirjam Zysman born the same date and lived at Brot 6 flat 2 and Goldschm 18. I did a third search and found Dworka Miriam Zysman born 28/09/1921 and she also lived at Brot 6 2 and Goldschm 18. I'm almost certain due to the similarites in the birthdates as well as the addresses they are the same person as Dorka Zysman.
I'm thinking she lived first at Goldschm 18 then moved to Lanziger 15, then moved on September 3, 1942 to Brot 6 flat 2.
I found Szrul Mordka Zysman born 17/12/1890 and Sura Zysman born 15/09/1888 all living at Goldsch 18. Srul died on July 19, 1942. I'm guessing they were Dorka's parents even though they are on the older side.
