I would appreciate suggestions. It’s hard finding another boy name we both love. So happy with [name]Oliver[/name], suits our son perfectly, even though it’s quite popular. What could we name his brother?
[name]Oliver[/name] and …
[name]Atticus[/name]
[name]Gideon[/name]
[name]Samson[/name]
[name]Charles[/name] / [name]Charlie[/name]
[name]Ezra[/name]
[name]Silas[/name]
[name]Henry[/name]
[name]Thomas[/name]
[name]Simon[/name]
[name]Leo[/name] / [name]Leon[/name]
[name]Milo[/name] / [name]Miles[/name]
[name]Morgan[/name]
[name]Reese[/name] / [name]Rhys[/name]
[name]Tristan[/name] / [name]Tristram[/name]
[name]Rowley[/name]
[name]Hugo[/name]
[name]Kieran[/name]
[name]Abram[/name] / [name]Abraham[/name]
[name]August[/name]
[name]Cassius[/name]
[name]Finn[/name] / [name]Finnian[/name]
[name]Ivan[/name]
[name]Tobin[/name]
[name]Oliver[/name] and…
[name]Henry[/name] - the first one I think of, but that might be too popular for you.
[name]James[/name] - another classic, popular name, but I love it.
[name]August[/name] - sounds nice with [name]Oliver[/name], I think.
[name]Theodore[/name] or [name]Theo[/name] - one of my favorites that I think is a similar style to [name]Oliver[/name]
[name]Toby[/name] or [name]Tobias[/name] - maybe?
[name]Nicholas[/name] - might be too popular as well (you could use [name]Nico[/name] as a slightly unusual nn)
[name]Rowan[/name] - slightly different, but such a gorgeous name, and has the same soft but strong image as [name]Oliver[/name]
[name]Lucas[/name] or [name]Luca[/name] - just another that might work
[name]Maxwell[/name] or [name]Max[/name] - slightly different style in my opinion, but could go well with [name]Oliver[/name]
[name]Archie[/name] - OK, if you don’t like nn names you won’t like this, but it’s sort of a guilty pleasure of mine
[name]Atticus[/name] - think this could possibly go well, too
[name]Oliver[/name] and brother…
[name]Sebastian[/name]
[name]Felix[/name]
[name]Hugo[/name]
[name]Theodore[/name]
[name]Inigo[/name]
[name]Simon[/name]
[name]Silas[/name]
[name]Gideon[/name]
[name]Timothy[/name]
[name]Leo[/name]
[name]Cassius[/name]
[name]Raphael[/name]
[name]Gregory[/name]
[name]Tristan[/name]
[name]Tobias[/name]
[name]Duncan[/name]
[name]Marcus[/name]
[name]Adrian[/name]
[name]Franklin[/name]
[name]Bennett[/name]
[name]Jonah[/name]
[name]Griffin[/name]
[name]Lucian[/name]
[name]Barnaby[/name]
[name]Damian[/name]
[name]Maxwell[/name]
[name]Miles[/name]
[name]Edmund[/name]
[name]Nigel[/name]
[name]Percival[/name]
[name]Rupert[/name]
[name]Stuart[/name]
[name]Tarquin[/name]
[name]August[/name]
[name]Dashiell[/name]
[name]Horatio[/name]
[name]Valentine[/name]
[name]Frederick[/name]
[name]Harvey[/name]
[name]Louis[/name]
Some of these will probably be repeats but…
[name]August[/name]- I think [name]Oliver[/name] and [name]August[/name] would make excellent brothers
[name]Hugo[/name]
[name]Milo[/name]
[name]Felix[/name]
[name]Julian[/name]
[name]Louis[/name]
[name]Miles[/name]
[name]Simon[/name]
Thank you all. I like the names you’ve suggested. Particularly the ones that are easy to pronounce for my French family. I will share with my husband and maybe come back with our selections so you can chime in if you please. 
[name]Finnegan[/name], [name]Maximo[/name], [name]Jax[/name], [name]Jasper[/name], [name]Caspian[/name], [name]Casper[/name], [name]Simon[/name], [name]Brock[/name]
I think [name]Harris[/name] would be adorable with [name]Oliver[/name].
