In entering Fajga Brylant in the search tool, Chana Fajga Brylant was the only name that came up, and she was born in 1931--which isin the age range possible for her to have signed the album.
I went through everyone with the last name Brylant and found people who lived at the same address. Every single person was deported on the same date (March 15 1942) as Chawa Fajga.
I found a possible mother, Sura Estera (b. 1902) and a possible father, Icek (b. 1897). I also found the names of 5 relatives close to Chawa Fajga's age--they are most probably cousins or siblings: Abraham (b. 1936), Chana Luba (b. 1924), Eleazar (b. 1926), Josef Noach (b. 1929), and Jakob Mendel (b. 1934). Again, all these people lived at the same address and had the same transportation date as our student.
According to the deportation date, March 15, 1942, there were daily transports to Chelmno that went on, and the deportees were all murdered in gas vans.
