Can you translate these given names into the nine featured languages: English, Dutch, German, Spanish, French, Italian, Polish, Finnish, and Portuguese?
The most common variations are accepted, which are determined by what the royal would usually be called regardless of his origin.
Thanks for your comment, but as the description says, the accepted variants are those that foreign royals are translated into. You can see that, for example, English and Scottish kings named James are rather translated to Jacobo. Also, as far as I've read, there is no consensus on whether Thiago and Diego are actually equivalent to "James" or "Jacob", even if they are sometimes used as such.
I would argue they are, since Santiago de Compostella for example is literally named for Saint James. Besides, Tiago and Diego are far more frequently given names than Jaime and Jacobo, so I think it should at least be accepted as a type-in. Otherwise, very cool quiz
