That's actually why the name isn't on my list. Other than being cutesy which I personally don't mind, I'd worry that maybe she would be very large and you just can't be large and be named Posy. It defies everything. Which, after saying that, makes me question myself and my perceptions of appearances and names. Hm.
I like the idea of Josephine as a full name for Posy and it's been on my list before. It just doesn't fit my tastes very well at the moment. Josephine keeps ending up in the middle since I can't think of an amazing middle name for it.
Thanks!
