I believe that the names Malka Etta Flajszhaker, Malka Etla Flajszhakier, and Malka Etla Flojszhakier, are the same person. The birth dates listed for the first two names are the exact same 12/9/1931. The date of birth is estimated for the Flojszhakier spelling, but the given year is 1932, which is only a few months apart from the other birth date. Also the addresses among the three records correspond, so I believe that all three records are from the same child.
The dates that I have added for the change of address and deportation were obtained from the inhabitants database. Although I used two different variations of Malka's last name, I believe they are the same child because they have corresponding birthdates.
I was able to find what I believe to be Malka's parents and siblings by searching under the Flajszhaker last name for individuals that had the same ghetto address. All of the names that I added resided at the same ghetto address. Her parents's birthdates correspond to Malka's age, as do those that I believe to be her siblings.
