On 25 February 2009 the extensive family and business archive De Jong-Bitgum was donated By Akke de Jong-Terpstra in Bitgum (Genealogy II.2) to Erfgoed Fundaasje.
As part of the care for business and family heritage in the Klaaiboustreek region, an extensive family archive has also been created, described, archived and digitized by Erfgoed Fundaasje. This is secured for the future and is stored according to agreements in climate-controlled vaults at the municipality of Waadhoeke. The archives can be consulted for research by appointment with Heritage Foundation.
The family tree below is set up so that descendants who do not bear the name De Jong are also included.
This wil never be fully completed, but below a lot of data is still missing. The source is as good as the family tree as it is included in the Report of the Brouwers evening 1970. Additions are appreciated.
