Delta Sigma Rho?
 

Okay, maybe I am going insane...but wasn't there a National sorority named Delta Sigma Rho?

For some reason I thought about them and looked the name up on Google and nothing came up...I was going to check my Baird's but it's currently packed away.

Am I going crazy?

Delta Sigma Rho was an honorary forensics group, merged with Tau Kappa Alpha.....
It a forensic fraternity http://www.mnsu.edu/cmst/dsr-tka/dsr-tka.html
That's the only national group I'm familiar with. There may be a local by that name.

There was also a group founded at Miami university called Sigma Delta Rho, defunct now...merged with Pi Kappa Phi, and Alpha Kappa Pi (which this group ended up merging with Alpha Sigma Phi)

Does this help?
