In a search for P* Rozenfarb, Frymet (Perla) was the only girl who came up that was born in the right time frame to have attended School #19A.
Also, underneath her address there was a note that said 'Stare Miasto,' which a google search indicated was/is the name of several city districts and villages in Poland, but it is unclear which one Perla came from.
Fryment/Perla lived at Brunnenstrasse 17 27 with her father, Wolf (b. 1880), and her siblings, including Jeszaja (b. 1927), Mojzesz (b. 1929), Rozalia (b. 1925), and Chana (b. 1917).
Information about Chana is a little less clear than with Perla's other siblings. There were three profiles I found for Chana, the first of which resembles her siblings in that it lists the correct Brunnenstrasse address, a complete birthdate (10 June 1917), and the fact that the family originated in Stare Miasto. The second profile lists only a partial birthday (10 June), gives only a partial Brunnenstrasse address (Brunnen 17), and lists a previous address (Sulzf 5 64A). The notes include a date (August 14, 1942), which makes me think that the AG in the notes for her, and maybe everyone else in her family, could indicate a move, and not necessarily a deportation because it occurs after March 25, 1942, the date listed for all the other family members. The third profile indicates Chana's other name, Chana Minc.
While the March 25, 1942 date could indicate a move, there were also daily deportations to Chelmno in March 1942, so I have included Chelmno as a deportation/death location, but I also indicated March 25, 1942, as a moving date. It is simply unclear what happened.
