I just received this link to a bio of a relative of mine, Dr. Oscar Ritchie. The bio mentions a sustained relationship with Alpha Phi Alpha Fraternity (KAPsi is mentioned as well, but it seems that he was a member of APhiA, though there is no information about when and where he became a member). Has anyone heard anything about him in relation to the fraternity?
