Student Profile: Moniek Albert

The names Moniek and Moszek seemed similar enough that they have a good chance of being the same boy. The information said that Moszek was a student (schueler) and that given his school #15B, his birthdate with most likely lie within 1928-1931. Although in this case the boy's birthdate is listed as 1932, it is close enough in range that I thought it could be very well possible, especially given that the birthdate given was incomplete. While researching the last name Albert, I found 4 kids, 2 boys and 2 girls, that all shared the same last name and street address. Although my search only included people with the last name Albert and first names that started with the letter M, I still believe that these kids all have some sort of family relation that should be noted. After Moszek, I found a boy named Mendel Icek Albert, born 5 Oct 1929. His ghetto address was the same, Sulzf 66 7. As for the two girls, one was named Marjem Albert. Her birthdate is 10 July 1922 with the same address of Sulzf 66 7.
The second girl is listed as Maria Albert. Her birthdate is also in 1922 with the same address of Sulzf 66 7. Like Moszek, her address also include A Hitler 157. She and Moszek also were the only two of the four that has concentration camps listed, and they were both taken in 1942. She was taken to Ausg ?.9.42.

A few notes:

I think Maria and Marjem are the same person, given that they have the same address and same date of birth.

AUSG is not a concentration camp, but rather means "deported" in German. The ?.9.42 means she was deported on an unknown date in September 1942.

Do you think Mendel or Moszek is the more likely candidate to have signed this name?
