Student Profile: Rywka Adamowicz

I believe Rywaka Abramowicz could have been the student that signed the album. She was born on April 15 1928, so therefore, she is in age range between 7 and 13 years old. I also believe that because there are many students with the same similar names they are all just one person. For example, there are several Rywaka Nacha Abramowicz, and their birthdates are pretty similar. Maybe, there's a small detailish mistake that causes to be several students named that way, but on the contrary could just be one person.
