Dutch term – Kwartierverlies

The term kwartierverlies literally means ‘loss of quarters,’ where ‘quarters’ refer to a person’s ancestors. The usual English translation is ‘pedigree collapse.’ Kwartierverlies occurs when the parents of a child are related to each other, so the same ancestors occur in multiple places in the child’s pedigree chart.

An example of pedigree collapse is the Roerdink family from Winterswijk, where first cousin marriages happened multiple times. Read more about the Roerdink example of pedigree collapse.
