Court reporter needs help with Greek name please!!!!!

[Lauren]

I am a court reporter in Jacksonville. In taking a deposition of a lady here in town her sorority is bought up more times than I really count. She is supposed to be in it in the natinal level, but I can not find it listed anywhere, including here. Of course, I do not know how to spell it, so that might be slowing me down somewhat If someone knows the correct spelling, you would be saving me a world of work. It sounds like Phi Fie to me. Any ideas will be greatly appriecated. Thank you.
