Character Name? (Narrowed down)?

I've narrowed down a list of names to two of my favorites. I can't really pick though. The names are Lena and Lillian.

Here's her description if it helps at all??:

-Artificial black hair (semi-permanent dye)

with hazel eyes (more brown than green), rises up to a good 5-foot-6-inches. About 14. She's on the run so she finds the most comfort in the woods and operates alone for the most part. She does have several secret allies that she prefers not to use unless in times of emergency (she doesn't work well with others-slows her down). She's a master mind in the art of stealing & sneaking around.

Yeah that probably sucked but names please? Help!
