Thank you both, Ann & Margot for the clarifications. As long as I have been coming to the UK, I really do not know much about the peerage. Just never interested me. Well, until recently. I knew nothing about Brian Masters until now. It was my friend who got me interested in the non-royal dukes, with his connection. Roy Strong is a good resource on the coronation. It is far more flexible and adaptable than many people think. Of course, most people have not seen one in over 60 years! I have only seen it on video. Should be interesting to see what they come up with for the next one .
I sold my coronet to a theatre group, and lend them the robes anytime they can use them. But they are so costly to clean, I wish they would just buy the things! [they do a lot of G&S so they come in handy at times]
The only reason I thought the Shaftsburys are dukes is because half the West End seems to be named after them. And, yes, Ann, that is exactly what I was thinking of, the murdering wife. And the heir who left his perfectly happy life as a club manager in NYC only to come back and die. I think his younger brother has it now, by total surprise.
