[name_u]Love[/name_u] the name Khol or [name_m]Cole[/name_m]! It’s a very cool name that makes me think of a quiet, shy, deep thinker that people want to know better Of course, if this isn’t your main character’s personality, you should still use it!
I like [name_m]Cole[/name_m] but I don’t like [name_m]Kohl[/name_m] too much, particularly with the sibling options you have. If the spelling of [name_m]Kohl[/name_m] made sense lexically and was surrounded with other [name_m]German[/name_m] or Middle Eastern names, but combined with names like [name_u]Dexter[/name_u], [name_m]Malcolm[/name_m], and [name_f]Iris[/name_f], it’s extremely out of place.
