After searching for 'G*' and 'Cederbaum' under all the parameters, I came up only with Gita and Gitla, both of whom lived at the same address and were born on the same day, so I have concluded that they are the same person. In addition, that birthdate puts them in the right age range to have signed the album.
Based on identical addresses, I have concluded that Gitl/Gitla had a father, Icek (b. 1886); a mother, Hinda (b. 1899) for whom there were two profiles, each a month apart (one for November 20, one for December 20); and a sister, Dyna (b. 1928).
Along with Gitl/Gitla, Dyna and one of Hinda's profiles has a deportation date listed as February 18, 1942. There is no corresponding deportation on the Secondary Sources list, so it is unclear what their fate was. There was no deportation information listed for Icek.
