[name]James[/name]: I think this is so handsome, and I can see [name]James[/name] and [name]Finley[/name] being brothers.
With a short last name, though, I think I’d personally go with a longer first name.
[name]Henry[/name]: I really love this, too.
[name]Levi[/name]: I prefer some of your other names, because with [name]Finley[/name] and [name]Levi[/name], I hear a lot of “lee.”
[name]Paul[/name]: I do think it’s handsome, but I think that some of your other names work better with [name]Finley[/name].
[name]Brahm[/name] (it is a diminutive form of [name]Abraham[/name] as well as a nod to the composer!): I knew a [name]Bram[/name] (nn for [name]Abraham[/name]) growing up, and think that works well with [name]Finley[/name]. I can’t see [name]Brahm[/name] with [name]Finley[/name], though. If your last name sounds like Kick, I think a longer first name would sound great.
[name]Kellen[/name] (this may be a bad choice, given or last name sounds like “Kick”): I love alliteration, but do unfortunately think that [name]Kellen[/name] Kick is a bit too sing-songy.
[name]Stellen[/name]: I think that [name]Stellan[/name] is a great alternative to [name]Kellan[/name], especially with a K last name!
[name]William[/name]: I can see [name]Will[/name] and [name]Finley[/name] as brothers, but if your last name sounds like Kick, [name]Will[/name] Kick sounds a bit like a partial sentence.
[name]Fox[/name]: I think that [name]Fox[/name] Kick sounds a bit blunt, and I’m wondering if “foxy” teasing will arise, or if teasing will stem from [name]Fox[/name] sounding a bit like Fcks. (I went to camp with a girl a girl whose last name was [name]Fox[/name]–I’ll pretend her first name was [name]Julie[/name]–and mean kids sadly called her "[name]Julie[/name] Fcks.") I know that teasing is unpredictable, but some names just seem to more likely to be teased than others.
From your list, I really love [name]Henry[/name] and [name]Stellan[/name] Kick with [name]Finley[/name].
If I can only vote for one, I’ll go with [name]Stellan[/name] Kick, because I think it works beautifully with [name]Finley[/name], and without having the same ending sound.
Good luck!
