Help naming friend's due baby (sex unknown, name beginning with K)

[VengefulKittyInTheManger]

My friend is 38 weeks and still hasn't decided on possible names for the baby. Her and her DP do not yet know the sex of the baby and already have one girl called Kadey.

After my raving about MN, she has left me with the challenge of asking you all to help with name suggestions.

All she has given me is that the name should preferably begin with K and it should be unusual, but not weird.

So - any suggestions please?

My little girl's middle name is Katinka

Was a bit nervous about it at the time as it is quite unusual, but really love it now and sometimes wish it was her first name.

She is 4.5 and adores her name.
