@Randal'Thor Not sure whether you’re being serious, but in case you are: U Notre Dame is an American university founded by French priests whose student body is now largely Irish-American because Catholicism.
I once did some digging into it for an answer here. But I guess I had an advantage from growing up in Britain and knowing some of that stuff already from cultural osmosis.
It's super confusing. So a duke could have "associated titles"? How? Do they just inherit them from people other than the prior duke? And can titles be passed down the female line?
Lots of these titles were created by monarchs at some point in the distant past. Some of them might have been merged by marriages (not sure about the female line thing) or unmerged by nobles with multiple sons.
For example, the "Duke of Edinburgh" title has only been created a few times in history. Before Prince Philip needed a title as the husband of the reigning monarch, there was no Duke of Edinburgh. I think now Prince Charles is the Duke of Edinburgh along with his multiple other titles (Prince of Wales, Duke of Cornwall, etc.)
@Randal'Thor To be fair, Notre Dame is not borrowed from the cathedral in Paris. The university is officially called "the University of Notre Dame du Lac" and there is a lake on campus called Saint Mary's lake.
There is another one called Saint Joseph's lake as well. I used to work at the seminary north of Lake St Joe. It was very annoying because I always had to walk all the way around the lake to get to my job, while the priests and seminarians just walked across it on the water.
While working there I was often asked whether I had ever considered that perhaps I might have a vocation. I greatly regret that I lacked the wit to reply, "Yes, but not in the priesthood."
Oh, also, my understanding is that Notre Dame in Paris is only a cathedral, while the main church on the campus of the Indiana school is a Basilica, tyvm. 😁
