Gender: girl
Thanks! I am trying to show what I had done so far but still indicate that I am not certain. So I used the identity database to find that there are many schulerein with the right birth years with the last name Opatowska/ski. Guta, Golda, and Pesa (or Pesia). However with Pola Negri as a popular silent film actress from earlier, I could see it as a nickname for any girl. It could be Pesa, but I'm just not sure of that.
