I read where one young woman claimed that Martha Stewart was in her GLO. Martha Stewart went to Barnard when there were no NPC options for Barnard Women.
I should point out, however, that it is true that Moses, Buddha, Beethoven, and Genghis Khan were all Phi Psis. I just don't remember which chapters.
ETA George Washington and John Jacob Jingleheimer Schmidt were also Phi Psis. I forgot about them.
