Think it's a brilliant idea Anne. With your already compiled information and eagerness to find out more, I'd be inspired to try and find out more about my locality.
I'm especially thinking about the taster you posted regarding The Knights Templars and St. Moreil (can't seem to manage to Google anything).
If it goes ahead, I'll try and contribute.
Edit: Just managed to Google information on St. Moreil local history on this site.
Seems to have a catalogued record of items of historical interest within your commune.
