Student Profile: Hanna Poznanska

There shows up to be two Hanna's with the same birth date and same address information except the last name is spelled with and "i" at the end for one and an "a" at the end for the other. It appears to be the same student based on birth date and address information.

Yes, this looks like a match. Note that Hanna appears to have moved from Tannenberg 35 to Hamburger Strasse 44 Flat 5 to Rauch Gasse 39 Flat 1 in the ghetto. One entry lists her as having registered at a new address on May 20, 1942, but the other entry lists this as the date of her deportation out of the ghetto. Also note that there is a girl named POZNANSKI, Chana Sura born 10/03/1924 who could conceivably also be our "Hanna." Although, that seems less likely.

From the Catalogue of Oral History Archives (USHMM):

Extent: 2 ration cards.
Summary: Ration cards issued to Hanna Poznanska and Felicja Poznanska [donor’s mother] in the Łódź ghetto.

This provides evidence of Hanna Poznanska being a donor to the archive, thus a survivor (with a new hyphenated married name).

From the Catalogue of Survivor Testimonies (Visual History Archive of the USC Shoah Foundation Institute):

Hanna was interviewed:

USC Shoah Foundation archives indicates that their interviewee has the exact same birth date as the woman listed in the Lodz Ghetto Database. They are certainly the same person.

Good research!
