We need a name that goes well with [name_m]Weston[/name_m], but at the same time doesn’t sound like we’re raising all cowboys. 
So far we like [name_m]Levi[/name_m], [name_m]Cooper[/name_m], [name_m]Grant[/name_m] and [name_m]Gabriel[/name_m]… which do you prefer, and which would make a lovely pairing with [name_m]Weston[/name_m]? Any other suggestions?
Thanks!
I think [name_m]Levi[/name_m] or [name_m]Cooper[/name_m] go well with [name_m]Weston[/name_m]
other ideas:
[name_u]Quincy[/name_u]
[name_m]Pierce[/name_m]
[name_m]Dawson[/name_m]
[name_m]Asher[/name_m]
[name_m]Tucker[/name_m]
[name_u]Emmett[/name_u]
[name_u]Spencer[/name_u]
[name_u]Blake[/name_u]
I like [name_m]Grant[/name_m] best. But here are some suggestions:
[name_m]Weston[/name_m] and [name_m]Dennis[/name_m] “[name_u]Denny[/name_u]”
[name_m]Weston[/name_m] and [name_m]Felix[/name_m]
[name_m]Weston[/name_m] and [name_m]Ramsey[/name_m]
I also like the suggestion of [name_m]Pierce[/name_m].
I like all the names you mentioned but…if you don’t want the second boy’s name to sound too cowboy’ish that rules out [name_m]Levi[/name_m] and [name_m]Cooper[/name_m]. Those two are all cowboy to me.
[name_m]Grant[/name_m] is great - it fits with [name_m]Weston[/name_m] and does not scream cowboy.
[name_m]Gabriel[/name_m] - I do love this name but to me this just does not fit with [name_m]Weston[/name_m] at all.
I love the suggestions of [name_u]Quincy[/name_u] and [name_m]Dennis[/name_m].
I’ll add:
[name_m]Sebastian[/name_m]
[name_m]Milo[/name_m]
[name_m]Nathaniel[/name_m] ([name_m]Wes[/name_m] and [name_m]Nate[/name_m] - so sweet!)
[name_u]Sullivan[/name_u]
[name_u]Barrett[/name_u]
[name_m]Jonas[/name_m]
[name_u]Tyler[/name_u]
[name_m]Brecken[/name_m]
[name_u]Evan[/name_u]
Aw, Mama, LET your boys grow up to be cowboys! 
I like [name_m]Levi[/name_m] and [name_m]Cooper[/name_m] but agree they do sound more cowboy-ish.
I like [name_m]Grant[/name_m] the best from your list!
I don’t love [name_m]Gabriel[/name_m] but [name_m]Gabe[/name_m] does sound good with [name_m]Weston[/name_m] (or [name_m]Wes[/name_m], not sure if you ever call him that).
I like the previous suggestions of [name_m]Pierce[/name_m] and [name_m]Nathaniel[/name_m] for you.
I’d also suggest:
[name_m]Garrett[/name_m]
[name_m]Miles[/name_m]
Good luck!
[name_m]Weston[/name_m] is a wonderful name! [name_m]Grant[/name_m] is my favorite from your list.
