My mom, her sister, and dad were in locals in college (the went to a SMALL private Lutheran school) so I am the first NPC that I know of. My step-fathers dad was a Sig Ep and his brother is a TKE (actually from my school too!). I think that is the extent of it though.
Same here if you need help dealing with the parents.
My dad's first response was "So you have colors, signs and stuff right? Aren't you just joining a gang then?"
Yes, he was joking.
ETA: Where is PSUSigKap and her super Sigma Kappa family????
