you are welcomed. We do care in Switzerland about queries. I can add that we do have full archives, librairies, this means that every canton has his town archives, his canton archives and so on. We could avoid war so usually we find births, marriages, death registers as far as many centuries. There are a lot of notarial archives to look at but this is difficult and may take long time. The point is that you have to know where to look at, what to ask the clerk.
Basadingen TG sowie Unterschlatt und Trüllikon ZH sind seit mehreren Jahrhunderten Heimatorte der Monharts.

Genealogy is easy with some brains, and your ancestors are grateful to you that you do remember then. After all we are something because others parents has worked or were successful before us ? Good luck Serge de MULLER Buenos Aires/Fribourg
