Cornelius Kolff-Breymann (Davos, Switzerland) is one of two sons of Olga-Maria Breymann-Kolff; the name Kolff was added to Breymann officially, as one of the last wishes of his mother Olga-Maria, in order to keep the Kolff-name of this important branch alive in the following generations. It is the Association’s intention to continue this line with Kolff-Breymann. This is possible because the family name Kolff-Breymann has been officially registered in both Germany and Switzerland. We are currently working on including the full details in the genealogy (see also De Colve XV).
