Please help with character names!?!?

I am writing a story and for once I am completely stuck with character names!! Can someone help?

First my heroine- young girl, strong, foccussed, good at her job (paper girl), not too good with feelings and takes everything literally, quite nosy and...

always wants to help. She has bright green eyes, a pretty face and straw coloured hair. She is quite pretty, but too foccused on work to think about that. She hopes to become a private eye. I wanted something pretty- and can be either common or really different and strange, but still believable!!! I was thinkin erica but I don't think it suit her what do you think? And I recently had the urge to go with verity...don't know why!

Then another character is a young boy, not too good with school, and at first doesnt like the heroine but after working together they make friends. Otherwise havnt decided his characteristics. I liked the name triston, but I don't think it goes with his character...

Help???

Grace and Jack
!!

I like those, I might use Grace as a surname, and I could well use jack... If I can't get anything I think I might go with either Verity or Felicity (they're both weird I know) which do you prefer??
Still open to suggestions though!

verity is better if you dont go with anything else

Annie is quite cute and pretty, or Tallis, or Imogen...for a boy, maybe Jacob, or Darryl or Lewis...
