Gender: girl
A search for 'I* Hopman' turned up two results, but Itta was the only girl and in addition her birthdate made her an appropriate age to have attended the Gymnasium and High School for Girls.
Itta lived at the Konigsburg address with her father, Israel (b. 1891), her mother, Alta (b. 1891), and her sister, Golda (b. 1922).
The family was deported on March 20, 1942, on which date there was a deportation to Chelmno.
