Unlike the other examples in this thread, I'll give you credit for that one.
Interestingly the article shows a way for upper-class people to signal upper-class-ness through names. The other kids all have a normal given name, and can easily fly under the radar. But once you start saying all of their first names, it's a clear signal.
(Because it is in line with how many European royals name their children.)
