So the Challenge is to have at least three European monarchs have their capitals and the majority of their population and land in North America before 1700. I'm going to say Central America and the Caribbean counts so everything above Panama is fine.

To be completely clear; these are supposed to be nations based in North or Central America but with a heritage in Europe. They can't be rebellious viceroyalties or other colonies; they have to be rulers in Europe deciding to go the Brazilian route over a century earlier (and a bit North) and having it be permanent.
