The exact spelling of Sara Moskowicz returned no results, but we did find a few Sara Moszkowicz's that fit within the time period of the school. One was born 16/11/1923, one was born 7/2/1925, one was born 3/4/1921, and the last was born in 1922. We tried to compare the addresses of the different Sara's in proximity to the school's address but we were unable to find them on the map provided by the website. Clearly this name was very common, and given the sparse information we cannot draw any significant conclusions on her identity.
