Doug Rozell's comments: "I used maps from 1975 and 1908 that indicated place names. The W.A. Baker (Springbank Consulting Engineers) map of 1975 states that many of the place names are of an historic nature; in many cases all that is left is the church or community hall eg Rosanna, Chesterfield. Many of the County planning and public works case files name them as well. In Upper Ratho (three houses) there is actually a sign on someone's lawn, "Welcome to Upper Ratho"; one of the houses used to be the hotel, the place being a train stop serving Ratho. In Banner there is a boulder at the corner with an inscription memorializing a post mistress of the hamlet. Many of the places still exist as rural clusters or actual serviced villages (Braemar, Drumbo). In short, I just collected place names for which there is some warrant. The title "historic hamlets" is selected for the alliteration, while in fact the places run all the way from serviced village to hamlet to rural cluster to ghost."
