To further throw a wrench into the works, if I recall my sorority history correctly, Gamma Phi Beta was founded as a "SOCIETY". So, we weren't a fraternity *or* sorority to start with! It was after the founding of Beta chapter that the term "sorority" was coined. Therefore, in the case of Gamma Phi Beta, it makes it even less likely that the word "sorority" referred to having had a man's help.
In spite of the slight hoohah we've caused, I do find everyone's contributions to the topic to be interesting.
