Searching for both 'Cwia' and 'Idek' under fuzzy parameters, I was able to come up with Cywia Idek, who was born in the right year ragne for her to have signed the album.
Cywia's parents, Litman (b. 1892) and Sura (b. 1898), as well as her brother Abram (b. 1931), were all deported on the same date, March 15, 1942, which coincided with a deportation to Chelmno.
