The "patriciat valaisan" which provides in particular the prince-bishops, was formed with families of old nobility but also with some families incorporated into the nobility either by possession of a right of jurisdiction either by membership to the "nobility of integration".
Tessin, before becoming a Swiss canton in 1803, did not form a political and administrative unit and there is thus no "nobility of Tessin" in a strict sense, however there are some noble families originating from this area.
