My relation lines, especially to historic persons, are changing all the time. Sometimes links that existed earlier suddenly are broken.
When I look for the reason it very often is a result of people adding historical persons to the tree without checking if they exists from before, and since they use names that varies enough from the already existing name, the new profiles are not flagged as duplicates by Geni.
It is much work to merge all the duplicate profiles. Sometimes new users of Geni can add hundreds of profiles that exist from before.
Very often I do not dare to merge the duplicates profiles because of the prominence of the profiles.
This should be a job for the curators, but we need a forum where we can report our findings?
The most recent I found, but did not dare to touch is
Håkon V Magnusson, King of Norway
and
Håkon V Magnusson, King of Norway
and
Håkon V Magnusson, King of Norway
and all their relatives ......
This is unfortunately not unique...
Best regards,
Bjart
