My grandparents were divorced. How do I add that information?
If your grandparents are in FamilySearch as well as their marriage date, you can click on the edit button between the couple and a box will come up where you can click on Add Event under the Relationship Event heading (see arrows in bottom image).
After you select Add Event, there is a drop-down menu, and one of the things you can select is Divorce (see arrows in top image). You can also add a date and place, and don't forget to save! Hope this helps!
