whoops i'm so sorry to say i'm a tad tired of Zavier & Xavier these days but hey that's just me, lol !

a few suggestions ;

Kynan
Kyan
Leon
Lucas
Ryan
Trent

If it helps at all we had no boys name right until i went into labour as DP & i too couldn't agree ... only thing we could agree on was what intial the name would start with so maybe that could be a start for you both (??)
