Why redirect and change the proper legal birth name of a French King from Henri to Henry. All it does is cause confusion with the other King Henry's of England etc.
It is the most usual name to find him under in English-language works; furthermore it is official Wikipedia policy, see Wikipedia:Naming_conventions_(names_and_titles) Andre Engels
- The thing is that the policy isn't about the most common usage in scholarly works, but the most common use amongst "normal" people. While I don't doubt that "Henri" is a more common spelling in encyclopaedias, history texts and so on, a Google search suggests the opposite: "Henry II of France" has a little over 1000 hits, while "Henri II of France" has only around 200. The idea is, I think, that people searching on the wikipedia are not likely to be scholars, and it makes sense to put articles where people are most likely to look for them.
- It's not a policy that I necessarily agree with, but it's a policy, and is better followed than ignored, I think. --Camembert
Accordingly, I will proceed to correct Catherine de Medici to Catherine of Medici. Right? .... DW (It also might be a good idea if "normal" people also learned through an encyclopedia how names are properly spelled.)
