Gender: boy
For W. Rozenykwiat I found Wladyslaw Rozanykwiat born 1 July 1924 and lived at Bier 9 flat9 and Bramman 28 and died on 1.3.43. His name was the best match since no other matches came up. There are two students who attended the Gymnasium who were named W. Rozanykwiat.
WLADYSLAW ROZANYKWIAT died on 1 March 1943 and I found Chaja Sura born 22 Feb 1890 living at the same address.
