I did a search on Josek Erlich b. 1929 and lived at Sulzfelder 64 A3 and Wielun, also note WYM 3.11.1 SULZF 62.
I also found a Josef Erlich b. 11/10/1929 and he lived at Sulfelder 62 5 and Siegfried 64. Also note AUSG 31.3.42 TR 3/2.
I believe that the Josek and Josef I found in stage 1 are the same person. My reasoning for this theory is because Josef lived at Sulzfelder 64 3A and every person I found under that address also lived at Sulzfelder 62 5. Here are the people that lived at both address'. Blima Erlich b. 1855 (possibly Josek's grandmother) Freidla/Frajdia Frania b. 17/04/1917, Szmul b. 23/05/1926, and Szlama/Schlama b. 15/09/1891 and Malka b. 1890 (possibly Josek's parents.)
I believe they were deported on 31/03/1942 on TR 3/2 and Szmul on 23/05/1943.

According to the secondary sources if Josek/Josef Erlich and his family were deported on 31 March 1942 they were most likley sent to Chelmno where they perished in the gas vans
