Just hoping that there were these two directories for Somerville. Can't find Hugh A. Killoren(Killoran)b 1868 MA with wife Mary on the 1940 Census. 1930 they are in Florida. 1933 Somerville directory he is at 32 Dearborn Road Somerville and the 1940 Somerville directory he is at 43 Holland.
I tried searching for him by name with no luck(did find his nephew indexed under 'Killeras')!! So I searched the census by ED and found the two houses but he is not at either one. So possibly he moved between 1933 and 1940. I did try searching for him by just first name with no luck either.
