I think I know where this 'literary' idea came from.
As you all know (& I checked, this is public info available
http://www.alphadeltapi.org/wsb/inde...=UIEXT_IPP_507 here on our website) Alpha Delta Pi used to be known as The Adelphean Society.
Well there is/was a literary society called "The Adelphian Society" (note the spelling difference) in Pennsylvania around the turn of the century--in NO way related to ADPi of course!
Probably there is some confusion about that.
