Naming conventions for the Dutch part of the tree

  • Please keep in mind that with a marriage in the Netherlands the wife keeps her own last name, so please do NOT enter the last name of the husband in the last name field of the wife (you can use is in the Display name and/or in the Also known as)
  • The Dutch do not have a middle name, so that field is used for patronymics (please put all given names in the First name field)
  • Please do not put a nickname in the First name or Middle name field, please put it in the Also know as field and if you want to also in the Display name
  • please keep in mind the Dutch can have a prefix name part that should be in lower case and should go in the Last name field before the last name (most common ones are: van, de, van der, van de). The Belgium's do not have this prefix field so they write the name parts all with a starting capital if it is a Belgium last name. This also makes a difference in sort order when sorting on last name.
  • Please user proper case (names start with uppercase letter followed by lower case letters (see to display in uppercase)
  • please use the default language tab if the profile has only Dutch names, only use the Dutch language tab if names are changed on emigration or when a historical profile with sources in multiple languages.

Access to Dutch speaking users

At the associated Portaal voor Nederlandstaligen (portal for Dutch speaking Geni users), you will find hundreds of registered users. However, your place to communicate with them is this International Dutch Portal. You need help with sources? You need an expert opinion? You want further collaboration or start projects with Dutch speaking users? If you have a request, please start a 'discussion' and formulate your question - someone will pick it up!


Most Dutch profiles use the default language tab and use only the Dutch language tab when the profile is known with different names in different languages (like a name change after immigration), but there are profiles that do only use the Dutch language tab. Please check the profile after merging to see if some data should be moved to another language tab.

If you merge a profile please try to solve the data conflicts and when you cannot please inform the managers.
When you solve name conflicts please try to keep all names (put them in the AKA field)
Data conflicts can be accessed from this list:
It can be hard to see data conflicts so it can help to install SmartCopy ( and configure it to show them.

Please be careful with the date format the Dutch use DD MM YYYY so when you see a conflict where DD and MM are exchanged there could be a problem with this setting: for one of the managers.

If you need some general help with merging there are some help links on this project (English version, bottom of page)

Access to sources in The Netherlands and Flanders

General Advice

Please follow the official records as much as possible.

  • Civic Registries. Under Napoleonic rule, government administration of birth, marriages and deaths was introduced in Flanders (1796) and The Netherlands (1811).
  • Church Records. Since 1563 (the Council of Trent), churches gradually introduced the keeping of birth, marriage and death records (abbreviated in dutch to DTB records). Transcriptions are available on FamilySearch microfilm (online).
  • Notary Records. These records often go even further back and contain genealogical information around land deeds, house sales, marriage contracts... Some of these are preserved in local archives (rarely online, but with interesting exceptions).
