Hi Louis, I happened to be checking old threads and found this one. I'm surprised that I didn't get a pop-up from Genealogy.com. I used to get them when someone responded to a message of mine.
I'm still a fence sitter about the book, I'm afraid. It sounds like you've found other means of finding out about your lines in the book. I find myself hoping that Ancestry will index the book and post it online. I had once tried contacting Laurens County to see if Mrs. Nash had any heirs (I know she was unmarried and childless) with the copyright. I received no answer.
