An Ancestor ID I know personally has incorrect info. There is no source noted. How/who do I notify?
Thank you for contacting FamilySearch Community. Any changes made to a person will have the contributor listed with the change. The contributor will be in blue. Click on the blue name and send a message to the contributor. A list of changes can be found in Latest Changes. We wish you the best.
In addition to what the mod suggested, if you have conclusions (and evidence) that disagree with what's on FamilySearch's Family Tree, and you're certain that you're looking at the correct person's profile, then you can correct what's on the tree yourself. (It's like Wikipedia: anyone can edit it, after logging in.) It's a good idea to document your conclusions by attaching source citations, and explaining anything convoluted on the Collaborate tab.
