And if they were royal? I suppose it depends. It might be the same. But more likely, I'd go a bit wilder. I might be tempted to go for some ridiculously extravagant, fake-intellectual ancient sounding names. I'd probably make my, probably very classically educated, SO do most of the work in that case but I mean something like this, possibly with even more middle names, I just ran out of ideas:
Illuminata Bibiana EudoraCandelaria Fortunata TerpsichoreDulcibella Concordia SalvatrixEuphrosyne Harmonia NarcissaAndromache Kriemhild OenoneCrescentia Euterpe Psamathe
But, if I'm honest, I'd be possibly even more tempted to just do nouns! To me they somehow clash with the idea of royalty but at the same time fit in with a wider rich people vibes, so I feel like my kids wouldn't even stand out that much and I love noun names:

Depending on how bored out of our minds we'd get, being rich, we might mix and match all the sets for that chaotic vibe I get from reading some rich people wikipedia entries.
