I found two possibilities for "Dawid Stryjkowski": the first is "Dawid Strykowski" born in 1927; the second is "Dawid Strykowska" born 1/5/1930. Both are listed as schueler and are within the correct date of birth range.
According to ghetto notes Dawid (born in 1927) was transferred on 28.2.42 on transfer 20/2 and according to secondary sources these transfers were deported to Chelmno and ultimately killed in gas vans.
According to ghetto notes Dawid (born in 1930) had a change of address, possibly being transferred to somewhere other than chelmno. Possibly a labor camp? In the next stage hopefully I'll be able to find more information on him.
