Kirrily is my favourite K name.
I'm partial to Katharine for a girl and Kieran for a boy. Ian, Kieran, and Lewis or Ian, Katharine, and Lewis. I know that Lewis is the Welsh version of Louis and I think Ian is the Welsh version of John. I think Kieran is Irish but it sounds great with Ian and Lewis. I'm partial to Katharine with the A in the center since it's how my name is spelled. I've been told it's an older, more traditional spelling of the name. I go by Katie to my family and Kate to my friends.
These are really fun names! You're giving me some great ideas. I agree, new_mama, I would only pick a K name if it was something we absolutely loved! :)
With Ian and Lewis..
For the boys:
For the girls:
We know a family with I,J,(Parents) and K (g) L,M (twins, g/g) and N(g)! They has K then picked L for one of the twins and someone noticed the Alphabet Thing - The found an M name for other twin then when little surprise came along, there was an N they adored.
