The other queens-by-marriage, Alexandra, Mary, and the Queen Mother, were all aristocrats in their own right, Camilla isn’t. Just a point. Of course, Princess Catherine isn’t either, but she seems more queen-like than Camilla to me.
Camilla has a much of aristocratic (whatever that means), background as most of the others who carry titles, including Diane. Both those two woman are direct descendants of Charles 11 through his very many illegitimate children. Indeed, it appears as if the majority of those who carry these silly titles trace those titles back to that source.
For some centuries it has been normal for the wife of the current King to be known as Queen. When it is female Queen (in their own right) their husband cannot be called King, as part of all these archaic rules state that a King is of higher rank than a Queen.
All so very silly, Lord this and Lady that.......Lots of cosplay on Saturday.
