Delta Beta Sigma - high school sorority

[SWTXBelle]

Going through my flooded garage, I found my mother-in-law's program for the 1933 Convention for high school sorority Delta Beta Sigma. It still exists, with chapters in Tennessee, Arkansas, and Louisiana. I cannot get a clear count for how many active chapters they have - 3, 4, and 7 are all referenced in different places on their website.
