How to delete a parent?
An entry (https://www.familysearch.org/ark:/61903/1:1:23MM-KQH) contains an "illegal" child. Only the mother's name is known by her given name and the name of her parents. By mistake these grand parents are indexed as parents of the "illegal" child. The correction of the child's mother is possible but the father can't be deleted. How to do this?
