My favorites are Iris, Winter, and Sky. Iris is a beautiful, underused flower name with a cool hidden meaning (rainbow!). Winter is very delicate, pretty, and evocative. Plus, it has some upbeat nicknames, such as Winnie and Wynn. Sky is fun, spunky, and beautiful, provoking an image of a little girl playing in the sunshine. I prefer the spelling Skye, but either of the spellings work great.
I like Iris, but I also worry that it might be too close to Indiana. I also like Tamsin from Cora's list.
