I grew up about 30 miles from Kenyon and it originally was all male. Kenyon has always been against women organizing sororities, and has done everything in its power to keep them away. If I remember right, the student government tried to block girls from having their club approved. When DG colonized, the school and the Kenyon President, snubbed them.
I read this article a while back, and it gives a pretty good account of what happened in the 80s and 90s.
