Maybe it is a town that used to exist, but does not anymore. Some map services (i.e., Bing) report the location of "Census Designated Places" (obviously a US term, but I'm sure there is a UK equivalent), some of which have not existed for many years. Example: "Bartonsville" in this map http://www.bing.com/maps/default.aspx?v=2&FORM=LMLTCP...
