Chapters 1-5 follow the Kolffs along the rivers in the Netherlands from East to West. Each page has a link to the next (and back), start here if you want to travel with the Kolffs along the rivers, over time (16th – 20th century). The chapters have been taken from articles in De Colve; they were contributed by Dirk Kolff, archivist of the association (CBCA XVIIIn). Translations to English by Marius Kolff, chairman, webmaster (CBCD XVIIw4).Apart from 1-5 there are some interesting chapters, which have not been numbered, because they don’t quite follow the historical route along the rivers: pages are equally interesting for the history of the Kolff Family.
