Gender: boy
Although, the search returned with a middle name the, first/ and last name match. The birthdate also lines up with the date he would have attended Gymnasium, and the gender matches as well.
According to his profile Menasze moved twice, first from Kreuz apartment 11 to 12, then to Mittel 76. He was deported in June of 1942, which, according to the secondary files charts suggests he would not have gone to Chelmno. Chances are he was sent to Aushwitz there were no other documented transports in the summer of 1942. We looked through 1210 people with the last name Rozenblum and found four other people who's birth dates work and all of the other information is a perfect match . Two of which we think are Menasze's sisters. The first is Miriam Rozenblum who was born 15-7-21, an age appropriate for a sister. The second is Rojza Etla Rozenblum born 6-9-19, who also could have been an older sister to Menasze. The second two people are definitely Menasze's parents, the ages are appropriate and they shared all three of the same addresses as well the same deportation date(which was also shared with the two potential sisters). The father, Szlama Chaim Rozenblum born 16-10-1890. The mother, Rywka Rozenblum, born in the year 1890. I believe we have exhausted our resources at this stage. All the documents of Lodz deportation suggest that there were no deportations in the summer of 1942. However, the database clearly shows that Menazse and his whole family were deported in June of 1942.
Re: I believe it was Auschwitz because, at this point there were only documented deportations to Chelmno, Auschwitz and Polzan. However, every where I have searched has suggested that there were no transports to Chelmno in the summer of 42 and Polzan was all male laborers. Seeing that Menazse and his whole family left on the same day I doubt he would have been sent to Polzan.
