After my sister put in 10 years worth of information on my mother someone just went in and deleted some of her information even though she had documents supporting her finding. Is there a way she can restore it without starting over? The person who did it wasn’t anyone related or we know. I think only the person who started the tree should be able to delete!
If you go into the "latest changes" area, You can click "show all". Now, when I just tried to do that I got an error. I get so many errors these days. Anyway, as I recall next to any of the actions, such as relationship deleted, if you look all the way to the right, there is a "restore" link. She can probably restore much of her information fairly rapidly.
Yes any and all changes for a person can be found in latest changes. Proceed to the last person with proper information or the person that has the wrong information and on the right side look for latest changes. Press the words show all and there you will find a verticle list of all of the changes and the name of ID of the person who made the changes. You can correct any wrong data using the edit word and then put in the correct data yourself and of course press the save button.
There is a Help Center article on using the change log to restore previous conclusions: https://www.familysearch.org/en/help/helpcenter/article/how-do-i-undo-an-incorrect-change-in-family-tree
It's a bit confusing, because steps 3 to 5 are actually subparts of the same step. (They explain ways to access the relevant change log, depending on the type of change you want to undo.)
