While I could not find much on Jechil Magnus' fate, I was able to find his very large family. If I am correct here is his family: Rucha Laja Magnus 1921, Abraham Ojzek Magnus 1919, Chaja Luba Magnus 1923, Szmul Hersz 1925,Mosze Iccok Magnus 1927, Eli Melech Magnus 1930, Ita Sura 1933, Rachmil Magnus 1937, and the assumed parents of Jechil, Bonsza Bacia Magnus (mother)1895 and Jakoc Lazar Magnus (father) 1892. While I know these are relatives because they lived in the same apartment, I am not sure if they are cousins to Jechil. Also, Bonsza and Jakob could possibly be he aunt and uncle. Under such hard times, it seems hard to believe that all of these could be siblings. However, it is possible. I am curious what you think.
