I like both of your [name]Luka[/name] combos miles before the others. TBH I really like all of your middle name suggestions, much more than your first names.
All of your names are quirky-cool. Some are unexpected and refreshing, like [name]Caledon[/name].
I do not at all care for [name]Asa[/name]. He is an unflattering biblical namesake, and although “[name]Ace[/name]” has a cool sound, [name]Asa[/name] is way too close to Ass for me (and likely for his future classmates). “[name]Ace[/name]” and “[name]Asa[/name]” are miles apart.
I would keep playing around… I voted for [name]Holden[/name] [name]Elias[/name] since it flows well and I enjoy seeing both in the real world. But [name]Mateo[/name], [name]Sebastian[/name], [name]Caledon[/name], and [name]Luca[/name]/[name]Luka[/name] are lovely. ([name]Luca[/name] is the dominant spelling), and I’d love to see what else you could come up with.
[name]Love[/name] [name]Asa[/name] and [name]Holden[/name]! [name]Luka[/name] and [name]Caleb[/name] not so much. [name]Asa[/name] [name]Caledon[/name] and [name]Holden[/name] [name]Elias[/name] are by far my favorites.
I love both [name]Caleb[/name] options.
I almost voted for [name]Luka[/name] [name]Tobias[/name] because I read [name]Luke[/name] instead, with the A I feel like it throws off the flow.
