Putting Goldwasser's name into the database, the only plausible fit that came up (based on age) was Chaja Bruna, so perhaps she signed with the initial of her middle name?
The people listed as her family all lived at the same place as Chaja Bruna, and were all deported on the same date (in addition to having the same last name.) I have found a father/uncle (Leib Arje, b. 1905), a mother/aunt (Chejwet, b. 1902), and two brothers (Abram Izrael, b. 1930; and Icchok, b. 1932).
They were all deported on the same day, March 15, 1942, which according to the Secondary Source list, was part of daily deportations that month to Chelmno. This is where I have concluded that this family was sent.
