I don't know ALL of my family's Greek affiliations, simply because my dad's side of the family isn't as Greek, so we don't really talk about it much.

Mom: Alpha Xi Delta
Grandmother (mom's mom): Alpha Xi Delta
Dad: Theta Chi
Grandfather (mom's dad): Delta Sigma Phi
Both cousins (mom's side): Sigma Phi Epsilon
Cousin's fiance (mom's side): ?
Aunt (mom's side): Alpha Omicron Pi
Uncle (mom's side): Sigma Theta Epsilon...and maybe a social one too...
Aunt (dad's side): ?
Uncle (dad's side): ?
Me: Alpha Xi Delta

So far, without talking to any family members, that's all I can remember.
