My favorite of your names is [name]Sawyer[/name]. [name]Judson[/name] feels to me like a made-up version of [name]Hudson[/name], and all I can think of with [name]Ace[/name] is ‘ace in the hole’. Some other ideas:
[name]Tate[/name]
[name]Jed[/name]
[name]Harley[/name]
[name]Cruz[/name]
[name]Orion[/name]
[name]Ryder[/name]
[name]Caspar[/name]
[name]Zebediah[/name] (not sure if you’re interested in another ‘Z’ name, but this is one of my favorites)
[name]Gage[/name]
[name]Remus[/name]
[name]Dallas[/name]
[name]Damien[/name] (maybe too close to [name]Zayden[/name] though)
For some reason [name]Cooper[/name] and [name]Leroy[/name] came to mind. [name]Zevi[/name] is cool, prn. like [name]Levi[/name] but with a Z. Idk if the two Z’s are too much for you though. [name]Conrad[/name] is also unique and has the cute nn [name]Rad[/name].
[name]Zayden[/name] and [name]Judson[/name] are way too close. It would be tough for people, including the parents, not to mix up the sounds. “Z” and “s” are similar sounds so the “s” in [name]Judson[/name] matches the “z” in [name]Zayden[/name] and they both have a d ini the middle with short vowel+n for the ending sound.
[name]Sawyer[/name] is by far my favorite of your names and my favorite with [name]Zayden[/name]! It feels much classier to me than [name]Judson[/name] and [name]Ace[/name] because of its literary background, but still playful.
