I’m not really in to Royal Weddings, but I get why this one is so ground-breaking.
But I found myself wondering about a minor protocol matter. Her Royal Highness, The Duchess of Sussex is American, and not Canadian, even though she lived for a time in Toronto. But if she had been Canadian, how would the Nickle Resolution have played out with respect to her titles as Duchess and Countess? Princess isn’t a peerage title, so I don’t think the Nickle Resolution applies there. And I suspect that the whole “title by marriage” rather than “title by honour” thing would be part of it. But, y’know, dudes who marry princesses (such as the Earl of Snowden) are often granted peerages. So the situation could come up. I suspect that parliament would just try to avoid the question if it happened, because they’d come off as wet blankets in royal wedding euphoria.
I find byzantine protocol things kind of interesting.
