I lived at 249 Dill Hall from 1961- 1966, and at no 60 from 1984-1991, so I have lived 'at both ends'. I do not know of any property then, or still existing, which might be described as a cottage, since that term indicates (to me) pre 1900.
We do have local history enthusiasts as members- who may know, and some who have archives of photos from the past. So - fingers crossed for you
