[name]Bo[/name] is having a brother or sister! We have girl name options but boys are tough. We want a relatively unique name that will go with [name]Bo[/name].
Girl options: [name]Lyla[/name], [name]Teagan[/name], [name]Rue[/name]
Boys: We like [name]Charles[/name] (nn [name]Charlie[/name]) but feel it’s too traditional.
Help! 
Not sure how unique you are looking for, but [name]Bo[/name] made me think of:
[name]Amos[/name]
[name]Rhys[/name]
[name]Everett[/name]
[name]Emmet[/name]
[name]Heath[/name]
[name]Flynn[/name]
[name]Flint[/name]
[name]Miles[/name]
[name]Milo[/name]
[name]Lennox[/name]
[name]Maddox[/name]
[name]Madoc[/name]
[name]Sawyer[/name]
[name]Sayer[/name]
[name]Silas[/name]
[name]Gideon[/name]
[name]Quentin[/name]
Thank you! Actually we did have [name]Everett[/name] as an option for [name]Bo[/name], so maybe we should re-visit that one!
I love the name [name]Bo[/name]! My father is [name]Bo[/name] and he has two brothers [name]Jack[/name] and [name]Ray[/name].
I like the following with [name]Bo[/name]:
[name]Finn[/name]
[name]Eli[/name]
Arn
[name]Enos[/name]/[name]Enoch[/name]
[name]Jan[/name]
[name]Dan[/name]/[name]Dante[/name]
[name]Royce[/name]
[name]Lyle[/name]
[name]Ty[/name]
We were thinking of [name]Raymond[/name] actually also after an uncle… [name]Ray[/name] is cute 
I know a [name]Bo[/name] who has sisters [name]Amity[/name] and [name]Bronte[/name]
Some ideas for boys: (I’m thinking cool surfer boy/scater dude names)
[name]Taj[/name]
[name]Ari[/name]
[name]Jude[/name]
[name]Van[/name]
[name]Calix[/name]
[name]Kai[/name]
[name]Sunny[/name]
[name]Finn[/name]
[name]Nico[/name]
[name]Pax[/name]
[name]Jeb[/name]
[name]Shaw[/name]
[name]Hart[/name]
Actually, [name]Ray[/name] is [name]Raymond[/name] and [name]Jack[/name] is [name]Henry[/name] [name]Jack[/name].
I love [name]Lyla[/name] with [name]Bo[/name]! Feels modern but pretty, which is the vibe I get off [name]Bo[/name] as well. For me, [name]Teagan[/name] is more trendy than unusual. I [name]LOVE[/name] [name]Rue[/name], but maybe it’s a little Hunger Games-y at the moment? You might also like [name]Etta[/name], [name]Alice[/name], [name]Lilac[/name] and [name]Clover[/name] (too many O sounds?).
[name]Charles[/name] rocks! FYI, if you’re really feeling it, most of the families I know with more unsual girls’ names have used classic, traditional boys’ names - it doesn’t strike me as odd.
[name]Raymond[/name] is nice for the family connection, and I think [name]Ray[/name] would make a sweet brother to [name]Bo[/name]. I like some of the suggestions you’ve got, too, especially [name]Everett[/name] - such a handsome name with sister [name]Bo[/name]! You might like [name]Jasper[/name], [name]Jett[/name], [name]Samson[/name], [name]Forrest[/name] (too Gump?), [name]Gray[/name] and even [name]Ransom[/name], too.
Best of luck!
