Working on my sibset

We are expecting another little boy! We already have ([name_u]Rex[/name_u]), 2, and are searching for another boy’s name that we love just as much and one that fits the same style.

I feel like [name_u]Rex[/name_u] is so strong a masculine without being macho and it’s also fairly unique, yet easy to say, spell and pronounce. Ideally the next little boy will have a strong name too, with a bit of uniqueness too.

Currently we have a few names that we like, but I would love some feedback and other suggestions.

Combos we like:
[name_m]Atticus[/name_m] [name_m]Hawthorne[/name_m] (nn. [name_f]Atty[/name_f], Hawke)
[name_u]Lawrence[/name_u] [name_m]Wilder[/name_m]
[name_m]Kaiser[/name_m] [name_u]Phoenix[/name_u] (would love something to replace [name_m]Kaiser[/name_m] with; maybe something not so harsh.)

Other names I like:
[name_m]Jack[/name_m]
[name_m]Maverick[/name_m]
[name_u]Arlo[/name_u]

Thanks in advance!

[name_m]Theodore[/name_m] [name_u]Rex[/name_u] and:

[name_m]Jack[/name_m] [name_m]Wilder[/name_m]
[name_m]Jack[/name_m] [name_m]Hawthorne[/name_m]
[name_m]John[/name_m] [name_m]Maverick[/name_m]
[name_m]John[/name_m] [name_m]Cove[/name_m]
[name_m]Henry[/name_m] [name_m]Atlas[/name_m]
[name_m]Henry[/name_m] [name_m]Torin[/name_m]
[name_m]Charles[/name_m] [name_u]Roan[/name_u]
[name_m]Charles[/name_m] [name_m]Flint[/name_m]
[name_u]Everett[/name_u] [name_u]Sterling[/name_u]
[name_u]Everett[/name_u] [name_u]Phoenix[/name_u]

I like [name_m]Jack[/name_m] [name_m]Wilder[/name_m], but I’m afraid that [name_m]Jack[/name_m] doesn’t really stand up well next to [name_u]Rex[/name_u]?

Maybe [name_m]Theodore[/name_m] [name_u]Rex[/name_u] and [name_m]Jonathan[/name_m] [name_m]Wilder[/name_m].

I really like [name_m]Jack[/name_m] ([name_m]Johnathan[/name_m] isn’t really my style) I’m just worried it would sound plain next to [name_u]Rex[/name_u]. I think [name_u]Rex[/name_u] and [name_m]Jack[/name_m] sounds cute together, but I would still worry about the differences in style.

I [name_u]LOVE[/name_u] one syllable names, so I am thinking how I could shorten the longer names. My husband loves [name_m]Atticus[/name_m] [name_m]Hawthorne[/name_m] and there are so many nicknames to go with that ([name_f]Attie[/name_f], Hawke, [name_m]Thorne[/name_m]) but I just don’t love any of those like i love [name_u]Rex[/name_u].
