Kasha is cute but I think it's a food, so it weirds me out a bit on a baby. Kaelan
John is also cute--it would be pretty unusual to see Kaelan, in any spelling, on a boy in the U.S.
Kerr Findlay Donald is gloriously Scottish, and I like Elgin and
Frank quite a bit, too. Wow, are there enough Kieran/Kyrans in the UK yet! I like
Korina and
Karlo a lot too.
