Abstract
The article recalls that before and after the Second World War there was a completely different situation in our territory in terms of population composition and land ownership. A large part of the territory of Czechoslovakia was displaced by the original population and the areas were resettled in a way that changed the national composition and size of family ownership and the boundaries between homesteads, previously carefully recorded in a stable cadastre.
After 1990, wild shifts and inaccurate records from the post-war era were corrected on the basis of a new measurement and comparison of written sources from the pre- and post-war era. The pre-war written sources often took their place during the period of wild displacement in the period 1945 - 1947.
Nevertheless, they can be traced in a gap. One of the clues for tracing is outlined in the paper on the example of the North Bohemian business family Priebsch, connected in particular with the construction of spinning mills in the Jablonec region.
