Geneaogy in CH is so easy, as each family as a Commune d'Origine, eg the original place where the family name was registered. All the birth, marriage, death, etc documents for each member of that family will be stored there. It has nothing to do with where you are born (although for some the birth and origin commune might still be the same). For instance I never visited mine until a few years ago- and yet all my documents are stored there, including the birth registration of my children born in the UK of a British father. So once you know your Commune d'origine, you have access to everything. Why not visit and discover it all in person?
