I did check E-Yearbooks website but only found Emmanuel (Boston)yearbooks for 1946-47-48-63. When I searched the Cushing Library catalog, I only got one hit, a yearbook for 1924. I think I found this citation in WorldCat also -I can check that source again and send any citations. BTW, do you know if the yearbook had a name and are you 100% sure that the college actually published yearbooks during the time frame in which you are interested?
As to obits, I do have access to "Boston Globe" obits via "ProQuest" Obituaries but that database only covers the period 1872-1922. I access it through my local library. Unfortunatley, I do not have access to "ProQuest Historical Newspapers" which covers 1872-1979.
Probably not much help but it is what it is........Rick
