Dad: Pi Kappa Phi (founding member at Seton Hall)
Me: Alpha Delta Pi

And that's it for my family! Apparently, a sorority (my mom does not recall which one, or maybe she just won't tell me?) tried to colonize at my parents' alma mater back when they were in college, and my mom would have been a founding member, but they couldn't quite get it off the ground.
