Usual Nickname, Unexpected Name--Nikki

How on earth did I do a Nicky-names post for boys, and not include some for girls? Shame, shame.
Nicole, of course, was a staple of 80s naming, and surprisingly, isn't too far out of the Top 100 today. Nicolette & Nicola are pretty recognizable variants, but what else can lead to Nicki?

(I also have to say, how amazed I am--whenever I do one of these posts, I discover some great names that really could work for previous UNUNs!)
