If you want to add a fact to someone in the tree but there isn’t a predefined type that fits the fact you want to add, then create a fact type of your choosing (a custom fact).
Adding a custom fact is easy to do.
Find the person in the tree you want to add a fact for.
On the left information panel, click to view the profile of the person you’re adding the fact to.
Then click on “Edit profile”.
Select “All facts”.
Scroll down to the bottom of the page and click the “Add another fact” button. In the window that appears, give the fact a name in the “Or, enter a fact type:” section.
Click OK to save.
