I don't know that any of my family really reminds me of FF characters. I have a friend that kind of looks like Irvine from FFVIII in the face, and I also have friends that I associate with Terra and Aqua from Kingdom Hearts. My cousin who got me into rpg's has the personality of Tifa and vaguely looks like a mix between Garnet and Rinoa actually. Those are the only real comparison's to anything Square related I can think of.
