Have you ever been surprised by another user’s edits on your Family Tree on the FamilySearch platform? Did you know you can avoid that issue, with a free private tree? While the CET was first introduced in the fall of 2024, it seems not many know about this helpful option.
Right now the CET feature is only available to selected users that sign up and are approved: https://www.familysearch.org/en/labs/docs/CETsLearnMore
FamilySearch’s User Owned Tree, or Controlled Edit Tree (CET), allows it’s users to create and manage private family trees on their platform, with all the tools and resources of their main tree. Until now, private trees have not been available on FamilySearch. While you could upload a tree with the Genealogies feature, it could not be edited - even by the owner.
While the CET can only be edited by the owner, others can be invited as collaborators. You have the option to make it public or private.
What makes the CET different than the main Family Tree?
Privacy options. You can choose to have your tree public, meaning that other users can view your tree, but they can not edit it - or private*, with only you and your invited guests able to view it. With the public option, living individuals in the tree are still hidden from other users. This public mode is the default.
Even with private settings, some items attached to confidential people are public by default, like memories. Be sure to review all privacy settings.
No outside collaboration, unless invited.
The tree may not necessarily start with you, unlike your access to the main tree. The API guide states: “a [CET] tree is not guaranteed to contain a person who represents the current user. Therefore, the concept of the user’s person may not be supported.” You can set a starting person when editing your tree.
Relationship views to self not supported, as no current user. Again, per the API guide for developers, “the ability to view a user’s relationship to persons in the [CET] tree is not supported because there may not be a person representing the user in the tree.”
Certain features not supported yet.
Not available to all users yet.
How to Create and Use a CET
Once approved, login and upload your GED file. (Need a GED? If you are trying this from Ancestry.com, you can download your GED file from your Tree Settings page). This process could take hours, depending on the size of your file.
Continue to edit the tree as normal. However, please note:
You must add sources! While the GED upload will create a citation, it will not copy over the file from other sources like Ancestry.com. It does preserve web links.
Also, when searching for records on FamilySearch, you must search from your CET to be able to attach the record.
You can access your CET anytime you are logged in from the Family Tree tab under CETs.
Optionally: add an image to your CET by clicking the black and white default picture, and uploading a new image.
It is not known when, or if, the CET feature will be available to all. We suggest subscribing to their blog for latest updates.
Though I immensely value the public Family Tree on FamilySearch for it’s collaboration and wealth of information, CETs are a good way for researchers to keep the integrity of their research without outside interference, and vice versa - CETs are also a way to explore possible relationship models or trees without affecting the main Family Tree data.
