About Jeno Yona Rooz
From Itzhak Itiel documents (1961)
"...I still remember, during the First World War, Yona, a nice man, an officer whose rank was Captain, was visiting his grandfather from Mirk (Menachem Mendel bohm), and his grandfather enjoyed the visit..."
[The famous picture of Menachem Mendel and Chava was taken by Yona at that visit -AM]
Part of the information is from testimony of the son Yehoshua in Yad Vashem
