Duplicates in historical records
I found the following obvious duplicates (apologies if this is a known problem):
The birth years are different but it is clear this is the same person: Charlemagne. (Actually I see in Wikipedia that nobody is quite sure what his birth year actually was).
Both records claim to be read-only, but both have been edited today. So I guess some people can edit, just not me. Perhaps somebody who can edit these pages can fix this? For such a prominent person, surely we only want one record in our database.
