Need help deciding on a name for my character?

The character is a high school senior and frankly, she's pretty ordinary so I don't want to pick a name that sounds really unique or glamourous. This makes it a little hard because, looking at my name list, I have like NO plain, ordinary names on it. I don't want it to be something common like Rebecca or Emily, but, agan, nothing to differant either. And one thing I really don't want is a name that sounds really sweet and girly because she's a very strong person and I want a really strong-sounding name, not something dainty and flowery. And no boys names for girls please.
