Project: Netherlands

Categories: The Netherlands | Netherlands Project


Are you interested in the Netherlands Project?

As of Saturday September, 4th 2021 the Dutch Roots Project asks of all it's members to stop adding the project as manager of profiles. This because we are waiting for the results of the discussion about new criteria for this before we want to add more.
It is recommended to place the Dutch Roots Sticker with the year in it.

The text below is temporary and will be updated further when the new criteria for Project Managed Profiles
and Project Protected Profiles are known.



The Project Netherlands (also known as Dutch Roots Project) is a project for and by WikiTreers interested in Dutch ancestors and their descendants. Together we strive to improve the accuracy and quality of the Dutch profiles. To support the members, offer information in Dutch and English and represent the Dutch vision within wikitree.
The project includes:
  • Persons born in the Netherlands
  • Ancestors born in former areas of the Netherlands in Europe such as:
    • The Habsburg Netherlands or Seventeen Provinces
    • The Seven Provinces
    • The Batavian Republic
    • The Kingdom of the Netherlands in Europe until 1831
    • The Kingdom of the Netherlands in Europe after 1831

Goals and Tasks

The general aim is to realize accurate and good quality profiles with regard to Dutch ancestors. Listed below are some primary tasks that an individual member can follow to achieve this goal for his or her ancestor profiles.
  • Primary tasks
    • provide profiles of your ancestors with reliable Sources.
    • Write a Biography and purge any Gedcom junk.
    • Provide profiles of Dutch ancestors that do not contain sources with the template {{Unsourced|Netherlands}}.
      The primary task of adding sources remains and can be done at a later time. For detailed explanations, consult the Help pages
    • Merge Duplicates
    • Optional Finished profiles can be provided with the Dutch Roots Sticker
  • Secondary tasks
    • Help WikiTree members with family tree research for Dutch ancestors by answering questions in G2G and Discord.
    • Try to connect Dutch profiles that are not yet connected to the common family tree by creating profiles of their relatives.
  • For fun
    • Join Dutch Roots Challenges
    • Create with other members community profiles of historically known individuals and connect them to our shared family tree on WikiTree.

Project Protected Profiles

In special cases, profiles can be protected by the Project Protected Profile (PPP) status. WikiTree Leaders can grant this status if the profile is part of a project and meets certain requirements. They are generally common profiles of historically significant individuals or profiles that are controversial. For general information click on: Project Protection. A PPP is recognizable by the logo in the top right corner of the profile and must be managed by a Project.
A profile belonging to the Project Netherlands is eligible for the status PPP and can be requested from one of our project Leaders if all of the following conditions are met:
  • The profile is arguably controversial or has been duplicated multiple times.
    Project security should only be used when profiles need protection, as they are often shared, often duplicated, subject to confusion, etc.'
  • The profile must fit within the Netherlands project.
  • The person was born before 1811, unless they meet Wikipedia's guidelines for fame. Notables.
  • The profile must be well documented and provide primary sources.
  • Biography has been cleaned of GEDCOM junk,, dead links, etc.
  • In case of duplicates, only the profile with the lowest WikiTree ID number with the correct last name at birth (LNAB) will be protected.
If all the above conditions are met, a request can be submitted to one of the project leaders of the Project Netherlands. The Project Leaders will ultimately assess whether the profile is assigned the status PPP or whether it is still decided not to grant a PPP.
Project protection includes:
  • Notifies the WikiTree community through a logo that the profile is protected.
    "Important edits should not be taken lightly and should be discussed in the associated project."
  • Protects the Last Name at Birth.
    The LNAB of a protected profile cannot be changed and the profile cannot be merged.
  • Protects the profile's relationships.
    You need to be a manager of the profile, a Project Coordinator or Leader to edit the parents, children, or spouses of a PPP.
  • Protects against casual editing via GEDCOMs.
    You need to be a manager of the profile, a Project Coordinator or Leader to edit a PPP using GEDCOMpare.
  • With the exception of the above, anyone can edit the profile, if open.
Project protected profiles must have the Project Account as profile manager and the Project Box must be installed.
See also PPP terms and conditions as described in the help page for Leaders Project Protection and Merging Profiles.


One of the advantages of WikiTree is that it offers the possibility to consult with fellow "genealogists", amateurs and professionals worldwide. Various communication channels are available for this. The main ones are G2G and Discord.


The G2G Forum is WikiTree's means of communicating related to family tree research.
G2G is short for Genealogist To Genealogist. This way you can use the extensive knowledge of active members of our project. We have experts in searching and especially finding reliable sources in the Dutch archives. We can also help you with the transcription of old writings and advise you on the preparation and design of profiles. So it is important that you know how to participate.

:Do you need help, ideas, questions or anything else? Don't hesitate, post a message in G2G FORUM Dutch Roots Project.

You can ask us questions in Dutch or English.


  • Go directly to: G2G ASK or go to G2G FORUM DUTCH ROOTS PROJECT and click on the "Post/ask Question" tab.
  • Place the tag Netherlands and/or Dutch_Roots or Belgium if it concerns Dutch or Belgian ancestors.
    If it concerns a specific profile, then put the Profile ID or the link in the appropriate box.
  • Choose a category.
  • Type your question or comment in the text box and send it.


Discord is an independent chat program where users can chat via voice or text. The Discord App is available for Android, IOS for Apple and Windows. :WikiTree started using Discord in early 2021.
Discord is great for lighthearted real-time communication, something WikiTree doesn't offer internally.
(G2G posts and profile comments are tracked in activity feeds and stored forever as part of our family history mission, so lighthearted conversation is generally discouraged) .

Last Name at Birth or LNAB

You often will come across the abbreviation LNAB around here, which means Last name at Birth. To keep things easy for everyone, we all decided that for Dutch Profiles to determine the most correct LNAB, we will use the Birth or Baptism record of a person, if this record shows the parent(s) only used a patronymic, the LNAB of this person is a patronymic as well, and if parent(s) used or were known by multiple generation patronymics according the record, the child also will receive a multiple generation patronymic for LNAB. If parent(s) used a last name already, that last name is the LNAB, etc.

Patronymics are in fact really easy, and you are not assuming one if you have found a Birth or Baptism record, because a patronymic always just is the first name of father + ending (the ending often depends on time and place), so if father in the Birth/Baptism record is named Pieter Jansz, the LNAB of the child is Pietersz, is father named Pieter Janszen in the record, the LNAB of the child is Pieterszen. (See here for more explaining about multiple generation patronymics.)

All later versions, and this can be many, because of the inconsistency in writing due to the fact they all wrote phonetically (so how they heard or understood things, that's how they would write), are added to the other last name field and the most current one (last found or taken from Death Record etc.) is added to the current last name field.

The inconsistency in writing also can result in different LNAB for children of one and the same parent, in one record fathers first name perhaps was written as Pytter Jans and in the record for the next child as Pyter and for the third child it might have been Pieter, so the first child would have Pytters for LNAB, the second Pyters and the third Pieters, for every child the other versions can be added to the other last name field though.

If there's no birth or baptism record we can compare earlier records of the parents, for example their marriage or other records, to see how their names or last names (if they used one already) were written, to determine the most correct LNAB for the children.

If there are none for the parents, we can look at the earliest record of the person him or herself, so for example his or her marriage record. But keep in mind that if this record is from around or after 1811 (the time when people had to officially adopt a last name !), he or she might have been born with just a patronymic, so if that's the case, early records for the parents are extra important to see if the parent(s) before 1811 also used a last name already or if parents only were known by patronymics. See also: patroniemen met een later toegevoegde achternaam Pre-1811

Also note that women in the past did not automatically adopt the last name of their husbands, so unless there are records showing the wife with her husbands last name we will not add it to the current last name field. See also: Patronymics vs spousal names

If there really are no records at all showing a persons LNAB (or last name) the LNAB is Unknown.

Location Fields

To be historically correct can be a lot of work and quite a puzzle because not only the names but also the regimes of places, provinces and countries due to for instance many long wars could change quite often and sometimes really quick, it also would mean we would have to create thousands of categories; we didn't. There are a few, but we prefer to (mostly) add the modern full (so no abbreviations !) location names to the location fields of Dutch profiles (to keep things easy and to make sure the location pin works) and if needed to add a link or perhaps a short explanation to profiles about the history of a location.
