Editing Distant Relationships
How do you edit a relationship to a grandparent or great-grandparent?
You can't do this directly. All relationships on WikiTree are from one profile to another. More distant relationships come from those nuclear relationships.
If an ancestor is incorrect, you need to isolate the parent-child relationship in the chain that is incorrect and remove that connection.
Removing Family Connections
Removing family members is done from the same edit pages as adding and changing them, described in the section above.
The one exception is siblings.
Sibling relationships are based on the parents. If two people share one or both parents they are considered siblings. To remove a brother or sister you need to remove the incorrect parental connection.
For example, let's say Child-X and Child-Y are listed as brothers because Father-Z is listed as the father of both of them. If this is incorrect, you need to remove Father-Z from being listed as the father of one of them. You can do this from the father's page or from the child's page.
