As those of you that have been working on completing street/place names in Switzerland know one of the more difficult parts is locating minor place names. I've been in contact with ortsnamen.ch which is a research project on historic place names and have received permission to use the data. The data has to be used with caution because, as said, it is mostly of a historic nature. but it can be helpful in any case.
