Hello Cousin,
I am directly descended from Willis Conner. His birth name was Willis William Conner and he changed the middle name to Jackson when he moved to Texas. I think that the book you were referring to in your post is the unpublished book "Judge Not". My cousin Jim Emerson has a decent copy of the original manuscript and at my last visit with him was trying to edit it. I read it and agreed with Jim that the author's style was indirect and wordy, needing editing. However, the information in that book and the research the author did was solid. I would love to hear from you regarding Willis' parents and siblings. I have his father listed as William but also heard his name was John.
