What do I do when your information on my ancestor is wrong?
You will need to give further details on where you are encountering this wrong information.
If you are referring to details recorded in Family Tree, you can edit any entry, although you should provide evidence and a reason statement for any changes.
If you are talking about FamilySearch records, you can sometimes edit these, but usually only where there is an attached image - and then only certain fields can be edited - e.g. you cannot edit an incorrectly entered sex of an individual.
Please provide a specific example of your problem in order to be provided with the best advice.
