A friend in KC told me that Shannon Vreeland, a member of the gold-medal-winning U.S.A. 4x200 freestyle swimming team, is a sister to a Gamma Phi Beta (Kansas State) and the daughter of a Gamma Phi Beta (Missouri State).

She's an Alpha Gamma Delta

Teri McKeever's late father was a Kappa Alpha at SC. Her late uncle, Marlin, was also a Kappa Alpha. Her aunt was a Delta Delta Delta. I think her mother was a Kappa Kappa Gamma.
