Greek Families

[DubaiSis]

I originally read it like 1stPhiDeltaAlpha did. I'd like to learn more about this as well. I get the families within chapters; that goes back forever, although the naming convention of daughter, mother, grandmother, aunt etc. has been change to little and big. But cross chapters? That's new. I wonder if that serves to foster Greek unity on campus and what purpose it serves.
