I had no clue how to pronounce Kuyper (would have guessed “Cue-per”). He will ALWAYS have to spell his name out for people. Kyper gets across the pronunciation you want (I’ve never met anyone with that last name, but I’m sure they’re out there), but it makes me think of a sci-fi novel and the words hyper and cyber. (I can picture him explaining his name, “It’s like ‘hyper’ but with a K.”) What about [name]Kyler[/name]/[name]Kylar[/name]?
[name]Brenner[/name] puts me in mind of [name]Max[/name] [name]Brenner[/name]'s Chocolate Cafes (delicious!), but I think the name is nice. [name]Brenner[/name] [name]Cael[/name] sounds a little better to me than [name]Brenner[/name] [name]Kai[/name].
[name]Crewe[/name] [name]Tobiah[/name] is the nicest [name]IMO[/name]. [name]Crewe[/name] is a great name (I like it without the e, too)! I think the sound is better with [name]Crewe[/name] [name]Tobias[/name], but I understand wanting to stay out of the top 1000. Perhaps you’d like [name]Tobin[/name]? [name]Crewe[/name] [name]Tobin[/name] or even [name]Tobin[/name] [name]Crewe[/name] sound sweet.
