I tend to agree with the deductions you made here based on the evidence. Stefan was deported from the ghetto on September 10, 1942. Since we know that there were mass deportations to Chelmno between September 5-12, 1942, it is a reasonable assumption that Stefan was among those killed at Chelmno. However, the secondary sources also indicate that the majority of those deported in the so-called Gehsperre action were children under age 10, the sick, and the elderly. Since Stefan would have been 17 years old, you may want to seek out evidence that he was in ill health to provide more converging evidence that he was a victim of the Gehsperre action. Also, in the future, it is not necessary to list change of address and deportations for the same date. The deportation date alone is good enough. Good work.
