Gender: boy
When searching for M. Friedrich there was only one boy who fit the age range 1921 and 1927 and he was Mendel Friedman born 1926 and he lived at Hausierer 8 flat 3 and Ost 72.
Found Moses born 1892 and Ittel born 1895 living at the same address and I couldn't find anymore information about Mendel.
