It's rather interesting I think that almost everyone's name idea has an I + A combo.
Very Junglesque
I noticed that when my first thought was Sia or Sya (See - uh), and then saw other people posting Tia, Mina, Fia..
I also thought of Kia or Kya (Key - uh), but that is very similar to
this. (Pronounced Kai - uh)I don't think the reference is necessarily a bad thing, though, as they both appear to be born to more native customs, and both (appear to be) separated from larger civilization.
Sia/Sya and Kia/Kya are still my top choices, though
Edit:
I also like Tsé, edited in response to Zelakon
Edit again:
I tried out that random name generator and I think I found some nice ones:
Nagi"Variant of the Arabic Naji, from an Arabic word meaning 'close friend'."
Tariro "Means 'hope' in Shona."
