On a lunch cruise on the RMS Segwin on Saturday the 15th, my husband and I got to see and take photos of the hospital where my mother spent 6 years being treated for TB (1946-52). I did not catch the name of the island where it was situated, and am interested in purchasing a book on the history of Gravenhurst, particularly of the sanitarium. Does anyone know where I could get a copy. I asked at Grace & Speed, and they suggested the library archives or a downtown bookshop as they had seen one with photos of patients in it, but we were late for a family dinner and could not stay longer in Gravenhurst to search for the store or library. As a result, I am searching on line so I can order one. Can anyone help me.
