Alpha Iota chapter of Alpha Delta Pi had 20 founders (I think) back in 1920, from the Sororsis Society (which was founded in 1915?). We only had to memorize the one founder, Louise Hetherington.
I had the opportunity to meet with Miss Hetherington several times, and she was a real pistol! I told her that we had made quota, and she said, "You better!" with a laugh in her voice.
She passed away about 5 years ago, and I felt quite blessed to have met her.
