Not all information that is kept in Dutch archives is available via national websites like WieWasWie or Open Archives. You can check the map of archives in the Netherlands to see where the records are kept for the place where your ancestors lived.
Often, the websites of the archives will have additional information. This can include images of the towns, finding aids with scans of unindexed records, or newspapers. You may even be able to find photos of the streets where your ancestors lived.
