I know this isn't the same situation. but Alpha Gamma Delta is the only NPC sorority at the U of Hawaii - Manoa...about 50 years after the alumnae chapter...now that's squirrel power!
I don't see why the closing of 1 chapter should automatically mean cancellation of the other one. Perhaps there was something about the 1 group that defeated itself along with outside forces.
Maybe some non-Greeks would be willing for a fresh start.
