K Names

Any K names that are interesting, not weird, but unique, pretty, and go well as a middle name with the first name Sydney and a one-syllable last name? Also, I'm looking for ones that hopefully don't look made-up (for example: Kourtnee) or are too trendy (for example: Kayla). Currently my favorite is Kasmira/Kasimira, but I want to expand this list. Extra points if it starts Ka-, but not mandatory.
Also, as a side note, any good nicknames for Sydney, that absolutely don't include Syd?
Thanks!(:

How about...

Kamden
Kalida
Katya or Katia
Kalinda (means sun in Hindi, so pretty)
Korilee

Hope that helped a bit ;)

Kennedy and Kaya are my faves

Kerensa or Kerinsa _Cornish name meaning, "one who is loved and loves".

Kayen is a cool name although I cannot find a meaning for it. (The Kay is pronounced like the Ki in "kite") It could possibly be related to a name like Kaya.

A possible nickname for Sydney could be CiCi, Ninny or Sissy.

I second unicorngirl's suggestion of Kerensa - although the only one I've ever met spells it Kerenza, which I also like.

Some more ideas (sorry for any repeats!):
