Two kids with k names....does the third need a k name?

Jessica
I have two kids from a previous marriage.  Kylie Brooke 6, Karter Wade 4.  I love K names and my new husband has no problem naming our child with a k to match the other two but we are having trouble finding a k name we both like that a family member or close friend hasn't already used. I guess my question is what would you do? Names we do like are Kourt Mason (b) Kate Madalyn (g) husbands grandmother was Mada. Thanks ladies!
