Bonboeken (from the period 1642-1811) in Leiden (Netherlands)

There may be errors in the data of documents. Copying data from (scans of) originals is human work. But computers that can read handwriting can also make mistakes.

If you find an error in the data you are encouraged to report it so that this can be corrected in the source at the archival institution or association.

If the information you find on Open Archives, is useful for your research, you can download it in PDF and GEDCOM format.

GEDCOM files can be imported into your family tree program. This way you do not need to type all the information in your family tree program.

Note: the files do not contain the scanned images!

In order to make use of this functionality, you need to have a subscription.
