I need your help!! what should i call my kitten?

My cat Lacie is pregnant and when she has the kittens i am keeping a girl and giving the rest to loving&safe homes. But im stuck on what to call her and i need help!! The names its between are Ivy or Mitzi (i thought they were such cute names!)

So which do you think? And do you have any sugestions?

P.s.The kittens could be any colour because the mum (Lacie) is black, ginger, a little brown and white (the colours looked like they are mixed) and the farther is brown (looks like tigar strips)

Thanks, XmichaelabX
