This is great information.
On a related subject, I found the church records for Canton Graubünden, Switzerland in Davos. The microfisch are open to the public, no fee, back to the 1600s or 1700s. I researched my entire family (when I was visiting there), mostly from Davos, but others from different places in Graubünden. They were very helpful to me at the "front desk".
Later, I drove around Graubünden, and took photos in the towns and villages where my ancestors had lived. Such a wonderful experience!
