I'd be quite careful about going too posh if you can as the other two are a bit more mainstream and they might want to move away! I'll suggest a few that I love anyway, all kings obviously.

Mm
I don’t want to give myself away
But two of the names are above and the other
Is Benedict.
ie the Benedictine libraries one of which is the worlds largest monastic library.

It also means The Blessed one

I am so curious to know the libraries you named your sons after! What a lovely idea

Edward, Henry and Joseph?

Rupert or Barney are great from your list, they seem to fit better with Edward and Henry too over the other ones

I don't think your wildcard names are 'out there' at all! Caspar is a great name. Quite like Rupert too.

Some random suggestions: Felix, Eric, Alistair, Conrad, Tobias, Robin, Xander, Ambrose, Louis, Tristan, Edmund, Otis, Cedric, Peter, Adam, Anthony, Benedict.

Could you not go wildcard with the middle name/s instead - go completely crazy with something like Horatio or Ptolemy etc to your hearts content? 🤣

It’s just that while I don’t think siblings have to match exactly, it does seem a bit unfair that his brothers get names that are popular (can get tat with their names on easily in shops, no spelling difficulties etc), internationally very well known/used, and impossible to tell age or background of them- but DS3 gets something without those benefits. He may love having a name that stands out more of course, but if he turns out to be a shyer/ introverted child…

Despite that, I admit of your list I do like elegant Caspar and quirky Rufus, though I find Barney childish sounding, Rupert wet and Percy nerdy, sorry 🤣

But maybe there’s a halfway house, if you don’t want to go Kingly anymore? (although I still think something like Alexander would fit right in - you could go unusual with the nn instead and go for Lex or Xand). Maybe also consider something classic but not quite as popular like Nathaniel, Owen etc?

I love the name Barney but they're all nice

Benjamin would be my pick for a ‘not matchy but sounds nice together’ name

Percy is terrible, he won't thank you for that. Have you never heard the phrase "point Percy at the porcelain" for males having a wee 😂

You could stick with King's e.g Charles, Albert

Or continue with Thomas The Tank Engine - Thomas, Gordon, Toby (or Tobias for 'posh'), Harold

Finally and my personal favourite, go for James then you have Kings and trains combined.

I like Rupert.
If you wanted to stick with kings, then Stephen* could be an option.

*I'm team Matilda.

From your list I would choose Rupert

Laurence or Sebastian
Laurie and Seb

I'm going to be honest, your list is far from my taste. Casper is the best of the bunch but it really doesn't go with the ultra traditional Edward and Henry. Rupert is probably the best match on your list, it's just not a name I personally like.

I think you need a middle ground of traditional but not popular. Something like Lawrence or Christopher would fit nicely. Possibly something like Dominic or Sebastian could work, or maybe go biblical rather than royal (or tank engine!), such as Zachary, Jacob or Benjamin? Joseph would go beautifully too.

If you want something a bit more 'in', what about Miles? That's currently quite popular but not such an obvious choice with Edward and Henry. If you want to go 'old school' (like Percy but without the tank engine link), I think Stanley would go well, or Frederick. Maybe Francis nn Frank?

Edward. Henry and Zachary. Jacob. Julien. Patrick. Otis. Sebastian. Lucas. Wilbur. Conrad. Roman. Kieran. Dexter. Ivan. Tobias. Cedric. Malachi. Xavier.
Arlo. Miles. Clark. Jonah.

Rufus and Barney I only know as oberused dogs names. Percy will have the Thomas the Tank Engine and Friends jokes. Rupert reminds me of the derogatory term in the army. So I'd say Casper the friendly ghost wins!

Rupert is my favourite.

Miles
Guy
Rafe
Conrad
Hugh
Piers
Justin
Benedict
Marcus
Victor

Definitely Rupert!

A great name that goes well with his brothers’ names. Congratulations!

Yes that’s true - I didn’t realise they are getting popular in some areas, they aren’t really used for babies round me (that I’m aware of).

I love the name Caspar. Also really like Percy and Rupert. They're my faves of your list.

Great list. Like all of them to a degree but prefer Rufus or Rupert (or Barnaby rather than Barney). Percy is a great name but not as simpatico with your other 2 kids names as the others imo. Caspar is my least favourite.
