The newest research tool for the genealogy is the internet. There are many sites on the internet that deal with Dutch genealogy.
Every day there are new ones added.
Many of the archives in the Netherlands and many of the large genealogical organizations have sites available on the internet. Here follows a list of some of the ones that I have found recently. Where possible I will indicate what is to be found on that site. This is the homepage of Arie Jan Stasse. It is also the site where you can find information on Gens Nostra and the Nederlandse Genealogische Vereniging.
