Technical Stuff

This error is checked only for public and open profiles with birth and death date set and Both parents defined. On private profiles, date precision is insufficient and would create a lot of false errors. Also profiles containing the Template:Multiple Births are excluded from checking. A profile must be unique in the combination of full name, birth and death date and both parents.
