Y'all are some serious night owls! :)

My sister and I are ladies of Delta Sigma Theta
My brother is an ice cold brotha of Alpha Phi Alpha

We were all ACEs of our line. ;)

AOII: Sister and Me
AOII legacy: my niece, Katie...she's three, but it'll happen one day!!
ZTA: Aunt

All at the same university. Not much, but it's a start!

myself: Gamma Phi Beta
mother: Alpha Xi Delta
cousin: Kappa Alpha Theta
cousin: Delta Tau Delta
^ cousin's fiancee: Alpha Delta Pi

I know there are a few more, but the conversation is usually "You were in a fraternity/sorority, right?" "Yes."

At least y'all have owls in common!

I'll go -

Me, my grandmother and great aunt - Pi Beta Phi
My sister and aunt - Tri Delt
My dad - DU
My cousins - 2 KA's, 1 SAE, 2 ADPi's, 1 Tri Delt
My Uncle - KA
Mother in law - KKG
Father in law - DTD
Husband - Sigma Chi
Son - KA

My mom mentioned that my uncle was Greek, but she couldn't remember which GLO... I'm not really close with him and he lives in Tampa, so I wouldn't know.

My 3rd cousin is a Fiji at my school.

That's about it. If my sons go to a school with a strong TKE chapter, then I wouldn't make it an option for them :p

Me - Kappa, duh
Bf - Theta Chi
Dad - Rho Epsilon, a real estate fraternity. Lol! He didn't tell me about it until a while into my local/KKG days.
Sis - I hope she goes Greek!!

my little sister (biological) just got initiated into DZ at sjsu last semester. dare i say i had an influence with her going greek.

children: it remains to be seen, but the family pin pillow is quite a collection! Many choices are there, though they'll likely be disowned if not AGD or SAE :D
Being Greek is not a new idea in our family!!!! It's a matter of where you fit best on your own campus!
