A name for the brother of Poésie?

I’m not expecting, but in the future, I’m planning to name my daugther [name]Po[/name]ésie. (Also considering the Norwegian spelling Poesi, as I’m Norwegian)

The name [name]Po[/name]ésie is French for poetry and is pronounced [name]PO[/name]-eh-zi, and I really fell in love with the name the second I heard it. For a potential sister I’m thinking maybe [name]Reverie[/name], but I do think that those two names are a bit too simliar with their -ie ending.

My problem is that I have no idea what to name a potential brother to [name]Po[/name]ésie.
I’m stuck. I like the names [name]Joah[/name], [name]Willem[/name], [name]Felix[/name] and Siver (the latter is after my best friend), but none of these seem to “go” just right with [name]Po[/name]ésie. Also boys names like [name]Rome[/name], [name]Valentin[/name] and [name]Ambroise[/name] are on my list.

As you probably can tell, I really like more of the uncommon names, rather than popular ones.

So, what do you think? What should a brother of [name]Po[/name]ésie be named?

First of all, I don’t think you should name a Norwegian girl [name]Reverie[/name]. It sounds like revehi (fox den) eller røveri (thievery), just saying!

A brother for Poesi (I think you should spell it this way, Poesi is stunning, and it’s pretty much pronounced the same anyways):
Eilir
Myske
Oleander
Petteril
Selje
Siderion
Sildre
[name]Silver[/name]
Sølve
Temir
Tindved
Villin

(For a girl: [name]Olivine[/name], Sivlilje, Rosea, Fiol, Soleie)

It depends. If you select the Norwegian spelling, Poesi, then I think a potential brother should have an equally uncommon, romantic Norwegian word-name. [And those are waters too deep for me. I’ll defer to @ottilie and @dearest for suggestions there].

If you do select the French form, then a brother should have something equally French. It needn’t be a word-name necessarily, but something that in Norway will sound similar. Here are some thoughts with a subtle nature connection:

[name]Blaise[/name]
[name]Cosme[/name]
[name]Clement[/name]
[name]Etienne[/name]
Leonide
[name]Lucien[/name]
[name]Maxence[/name]
[name]Olivier[/name]
[name]Pascal[/name]
[name]Placide[/name]
[name]Renard[/name]
[name]Victor[/name]
[name]Yves[/name]

I would name a sister [name]Astoria[/name]

I would name a brother [name]Dorian[/name], [name]Abelard[/name], or [name]Rhodes[/name]
