It is preferable to use the individual Burgerlijke Stand Sources to document post-1811 Births, Marriages, and Deaths. The Burgerlijke Stand Sources here on WeRelate take the form: Gemeente, Provincie, Netherlands. Burgerlijke Stand (for example: Source:Ferwerderadeel, Friesland, Netherlands. Burgerlijke Stand).
From the Site Information Page: The information in Genlias is taken directly from the Civil Register, the most important Dutch source for genealogical research. Since 1811 the most important events in the life of every person resident in the Netherlands – birth, marriage and death – have been systematically recorded. Marriage records from all provinces are currently being entered into the system. After that most of the participating archives will start entering records of birth and death.
