What are some alternate spellings for the name "Bahia"?

I’m trying to find a friend of mine from long ago named Jim Lott, but after about 30 minutes or so of googling, facebook and myspace I can’t yield any results. I decided to go for searching for his sisters (He has three, though I believe I’ve only met 2).

One of them (the younger) was named “Bahia”, only, they didn’t spell it like that. The spelling of her name, I want to say, had a “J” and a “G” in it somewhere.

What are other ways to spell “Bahia”?
