Squadron Recruits

[Niwashi]

I know the comments stating why a recruit joined is based on which challenge log led to getting them, but are the recruits themselves (name, race, looks, etc) based on it as well? I'd thought the rest was random (from amongst a collection of possible recruits).

PS: I'll extend my question to all the people who have obtained Femroes recruits, please tell me from what type of content yours was from. I want to make a full Femroe squadron.

I got one from a Gold Saucer challenge (one of the mini-game challenges, either "Size Doesn't Matter" or "From Small Things"). I'm just not sure if that's relevant.
