Brinkley Corbitt research

While reviewing all of the postings on this site for Brinkley Corbitt and his probable father, Joseph, I have seen that there were some papers or books written and a lot of information developed.But, I can't find any of those folks who said they have the information.All of the emails addresses are expired.Does anyone have some of this material that would be willing to share it?Help out a cousin in need!
