Alright, so it's common knowledge that many members of the British Royal Family have their own unique titles, such as William, Duke of Cambridge, Camilla, Duchess of Cornwall, etc. My question is, when displaying the royals in my tree, would it be best to use "of Cambridge" for the surname, or the generic "of the United Kingdom"? I know that this is largely a matter of opinion. I'm also aware that some people prefer to use the House name - Windsor - as the surname, which I am not doing. I'm just asking for advice and opinions on what the best way to go about this is. Thanks!
