There were two profiles for Perla Szajn, that were unified by one address (Inselstrasse 15), but the birthdates were off by exactly one month. Nonetheless, I believe the two profiles are of the same person. One profile indicates two addresses (Richter, Insel), and the other profile indicates three (Insel, Schlageter, and, according to the notes, a move on May 28, 1941 to Mickiewi).
Many of the members of Szajn's family have two profiles, one that indicates two addresses (Richter, Insel), and the other that indicates three (Insel, Schlageter, and a move to Mickiewi). Perla's date of birth differs by one month in the two profiles, as does her brother Abram/Abraham's (Jan. 9 and Feb. 9).
The family's deportation date is listed as March 28, 1942, which is the date (according to Secondary Sources) of a deportation to Chelmno, so I believe this family was deported to Chelmno.
I believe Dawid Icek (b.1898) and Chana (b. 1898) were her mother and father, Eliezer (b. 1927) could be her older brother, Abram/Abraham (b. 1932) could be her younger brother, and Chaja (b. 1935) could be her younger sister.
