The Annapolis Valley Regional Library or the Dr. Frank W. Morse Memorial Library (Lawrencetown) may have obituaries for some of these people which could lead to living relatives. The town of Middleton at one time had a weekly newspaper but I am not sure of the years.
Roop's funeral Home in Middleton is a family business and still exists.
there are 2 cemeteries in Lawrencetown but they aren't on line.
Hopefully, you are getting closer to finding a living relative that may have some family pictures.
With Watson being a druggist and his son a merchant, there will probably be obituaries for them or some information in local books that may have been written by local people on the town histories.
Midleton also is home to the MacDonald Museum which may have some information as well.
