Switzerland Zürich Church Records
In the Parish of Rheinau in Canton Zürich many marriage entries can be found from people from many other areas, such as Baden, Württemberg and Bavaria in Germany and Bohemia, Moravia and Tirol, as well as Elsass and France. This is because Rheinau was a beloved place for weddings. In fact marriages for non-citizens were 3 times more common than for residents. This had to do with the beautiful surroundings which would make a beautiful setting for weddings.
