I would not argue the point. I am not descended from that line and what I have in my files came from other people. I remember that a lady (deceased 1980) shared some McCracken information with me because she knew I had a McCracken line. Her interest was Wofford. I am sure that neither of us verified the material which was photocopies from a book.
My personal line is John C. McCracken married Dicey Oliver on October 22, 1835 in Jonesboro, Washington Co. TN Their original marriage license was in their grandaughters's family papers when she died Apr. 22, 1967. (my aunt has this original license - Mother has a copy from Courthouse)
