So far I have thought of [name_m]Thomas[/name_m], but would like other suggestions. Last name has a hard k sound.
Would you consider [name_m]Kaius[/name_m] ?? NN:[name_m]Kaius[/name_m]
[name_u]Kai[/name_u] [name_m]Xavier[/name_m]
[name_u]Kai[/name_u] [name_m]Nolan[/name_m]
[name_u]Kai[/name_u] [name_u]Jamison[/name_u]

[name_u]Kai[/name_u] [name_m]Gabriel[/name_m]
[name_u]Kai[/name_u] [name_m]Solomon[/name_m]
Thank-you I like [name_m]Nolan[/name_m]. I prefer [name_u]Kai[/name_u] because of the meaning. We live on an island surrounded by lots of [name_u]Ocean[/name_u] 
I think [name_u]Kai[/name_u] [name_m]Alexander[/name_m] would be a very handsome name. I wish I could use [name_m]Alexander[/name_m] for a MN but my cousin just took it as a first name. 
I love [name_u]Kai[/name_u] [name_m]Thomas[/name_m]! Two of my all time favorites

Lol. I just suggested [name_u]Kai[/name_u] in a reply I just made!. [name_f]My[/name_f] little brothers best friend growing up’s name is [name_u]Kye[/name_u]. I like [name_u]Kye[/name_u] [name_m]Louis[/name_m]. I also like the suggestion above mine, [name_u]Kai[/name_u] [name_m]Alexander[/name_m]. I also like:
[name_u]Kai[/name_u] [name_m]Daniel[/name_m]
[name_u]Kai[/name_u] [name_u]Mason[/name_u]
[name_u]Kai[/name_u] [name_m]Brody[/name_m]
[name_u]Kai[/name_u] [name_m]Maxwell[/name_m]
[name_u]Kai[/name_u] [name_u]Tatum[/name_u]
[name_u]Kai[/name_u] [name_m]Ross[/name_m]
I really like [name_m]Alexander[/name_m] too, but it is already taken by another family member 
[name_u]Kai[/name_u] [name_m]Louis[/name_m] sounds awesome! It would be on my list except I am not crazy about the meaning.
