And by the why, is he going by the alias Prince here in the US? Isn’t he just Harry whatever of an inbred British family?
I think that he is 6th in the line of succession, and that is all that English law allows, which is the *real* reason their son is not a prince, etc.
However, when Charles ascends to the throne, if William does not have another child, then Archie will be sixth and entitled to all that Megan wants for him.
