I've been trying to find out which sorority Katie Lorenz was in. Interestingly, she's from Michigan and competed in the Miss Michigan pageant in 2005 and 2007. I can't find a reference to her sorority though.
Found a reference, looks like she's a Delta Gamma:

Looks like Emily Cox is an ADPi from UK
Emily Cox, senior member of Beta Psi, was recently accepted into University of Kentucky Pharmacy School. She was also crowned Miss Bowling Green, and will compete for the title of Miss Kentucky this summer.
