Student Profile: M. Dajtelcwajg

So when I searched for M. Dajtelcwajg the best possible match I found was Meir Lejb Dajtelcwajg born 27 Nov 1932 and he lived at Hohens 21 flat 59 and Oststrasse 50. He had a ghetto note that says, UMG IN W33 1.11.42". I know UMG means Relocated/moved but I'm not sure what IN W33 refer to? I decided to look at Majer Lajb Dajtelwajg and I believe he and Meir are the same person given the fact they were both born on 27 Nov (5 years apart) and lived at similar addresses. However, if Meir/Majer was born in 1937 he would have been to young to attend School #15A. I also found him listed under Maier DEITELZWEIG born 27 Nov 1938 and living at Schneiderstrasse 9 flat 3. I'm really curious as to why he appears in the database with 3 different birth years.

I'm also curious why he appears with three different dates of birth. Is there anything in the next stages that might help clarify which date is correct?

I found Izrael born 15 Jan 1901, Szajndle born 1899 she also appears as Krajndel born 1903, and Mordchai Hirsz or Mordcha born 1 March 1936 and Deported 10 Sep 1942. If you look at the ghetto not for Krajndel it says, "W Dzien Wpisu Znajdowala Sie Zgierska 21." My Polish isn't great but I do believe it means, "The day of the entry was Zgierska 21." I'm not entirely sure what this refers to. Was the family living at Zgierska 21 when their information taken? I couldn't find anymore information on Meir or Szajndle/Krajndel. Mordchai was deported during the Gehsperre action and Izrael was sent to Dachau where he died on 10/01/1945.

Based on the expert reviewer's notes, we can only mark this as possible until we know with greater certainty who signed this name in the album.
