There are thousands of sites that are helpful for researching your ancestors from the Netherlands. This list contains my 10 favorites. I have limited this list to websites that would be useful for people who don't speak Dutch, which means they are either available in English or self-explanary.

1. Genlias
   Genlias is the largest genealogy database in the Netherlands. It includes information of over 40 million people, mostly covering the 19th century. Select 'English' in the top right corner of the homepage for the English version.
2. Digital Resources Netherlands and Belgium
   This portal provides links to records that are available online. These can range from name indexes and transcriptions to digitized original records.
3. Archivenet
   Archivenet is a portal that provides links to the websites of all the Archives in the Netherlands and Flanders.
4. Wat Was Waar
   'Wat Was Waar' means 'What Was Where'. The websites shows the digitized 1832 plot maps including the lists of owners. You can zoom in on the map and click it to see a selection of maps from that area. Scans from the information about the owners of the plots are available as well. These are called OATs (Oorspronkelijke Aanwijzende Tafels, original referring tables). For different regions, several other types of maps are available as well.
   
5. Nationaal Archief
   The website of the National Archives contains several thematic databases, including emigrants to Australia and freed slaves in the West Indies.
6. Memory of the Netherlands
   This large image database shows the highlights of the collections of many cultural or historical organizations in the Netherlands. One of the themes is the Atlantic World. Select the EN-button in the top right for the English version.
7. Stamboomgids
   This portal is in Dutch only but the Familienamen (family name) section is easy to use and provides links to websites about specific family names.
8. Family name database
   This database shows the occurrence of Dutch family names based on the 1947 (most recent) census. Fill in a naam (name)  and click the Zoek (search) button. A list of names will appear. Select ‘kaartweergave’ (map display) to see the geographical spread.
9. Trace your Dutch roots
   This website has some great research tips on Dutch genealogy. It also comes with a weblog.
10. Dutchgenealogy.com
    This website has an online shop with Dutch genealogy items, a knowledge base and online resources such as 1860s maps of all the municipalities.
