Given name: Anka Family name: Wołkowicz

The author went to visit Anka Wolkowicz, who knew the yard better then her and could know some hideaway. It occurred that she knew the hideaway, but it was impossible to get there. Anka was captured during the round-up (kociol) in Mila Street and was deported to Treblinka.

The entry on page 89 suggests that Anka could have been Mania Wasser's daughter (or there is a comma missing in the sentence)
