Rowan County Public Library has an extensive "History Room". If you have never been, it is worth the trip if you are researching early North Carolina history and families.
I spent from 10 a.m. until 2 p.m. there and could spend days there. They had a specific sections for family research, NC counties, Salisbury newspapers, Virginia research and more!
I confirmed several things that were only theories for Conner research and look forward to going again really soon.
My wonderful mother-in-law was related to the McCanless family and I found a wonderful book that I would love to own. If anyone knows of a copy of The History of the McCanless Family in the United States for sale at a reasonable price, please let me know. It includes the documentation of her relative - D. C. McCanless murder trial when Hickock and two others were charged with the murder!
Many theories as to where the Conner family came from exist and that they were O'Conner/O'Connor before becoming Conner/Connor.
The puzzling thing is that in 1840 there is only one (1) O'Conner/O'Connor shown in the United States by Ancestry.com. That O'Conner/O'Connor lived in Maryland.
By the US Census, the Conner/Connor families were already established in the Carolinas with Conner families in the 1790 Census.
I would love to hear you thoughts on this idea and suggestions for further research.
