I accidentally merged two unrelated people. How do I separate them and bring the deleted person back?
The great thing about FamilySearch is you can fix mistakes. On the right hand column go to Latest Changes and click on Show All. Click on the name of the person who was deleted when you merged. In the pop up widow click on Person. In the square labeled Person Deleted in the right hand lower corner in blue it says Restore Person. Click it.
Then go back and make sure the sources are correct for both people. I sometimes find mistakes there after unmerging.
carol.s.johnson - If you or somebody else has made edits to the "survivor" of the merge, then the un-merge function will no longer be available. This video will explain what steps to take = "How to Repair Incorrect Merges in Family Tree - Kathryn Grant" - https://www.youtube.com/watch?v=e3wVkWt581Y
