Need help choosing a new name for my character?

Okay, so I need help picking out a new name for my character. In the story, she's about eight years old and the daughter of the main character. She's a very bubbly, bright little girl who absolutely loves her father and is very optimistic about life, despite the fact that she doesn't have a mother. For reasons I won't name here, I have to change the name I've given her. I originally wanted to call her Maemi, which is Japanese for "honest child." The main character names her that because he wants her to remain pure to herself and her own feelings. Her mother essentially is out of the story (for sanity's sake, let's say she's passed away), and I want to give her a similar name of a different language of origin.

-I want to give her a name of English, French, American, or maybe Italian origin

-Originally, I had chosen the name "Kaitlin" because it had a similar meaning, but it just doesn't seem to fit her.

-I want her name to mean something along the lines of:

Purity

Honesty

Love (her mother's name means "love" as well, so it would be cool if she had a name of similar meaning)

Blessing

or something along those lines.

-The name also should be not-so-common (Kaitlin and other related forms are actually not that rare (I've met a couple of "Katherine"s in my life and one "Kaitlin"). Even in Japanese, Maemi isn't the most common name, which made it kind of special. So her new name should have that air of "not everyone has this name so you deserve it because you're a special sort of girl," I've consulted several baby name websites and such, but there wasn't a name that stood out as "the one." If you could provide me with some suggestions, that would be awesome. I will choose best answer.:) Thank you very much for helping.:)
