Hello. I didn't find a Walter Ziemba obituary but I did find the 1962 obituary of a Mrs Walter J. Ziemba of 836 Stanley Street, New Britain, CT. Her name was Olga (Biella) Ziemba, she was 45 and surviving were her husband and two Biella brothers, no children mentioned. Would you care to have that obituary?
I see that you are also looking for a Mr. Stanley Duchnowski of Norwalk, CT. In case you are not certain that he is the one you are really looking for, I found the Nov 25, 1958 obituary of a Stanley Duchnowski of New Britain, CT. It reads that he was 45 and born in Poland and left a wife and two daughters there. Would you care to have a look at that obituary as well?
