Overall this is a good book with a lot of high level information on the life of a "bigger than life" folk hero. They even go into the facts vs the legend vs the TV myths. The book is well done.
I do however have to challenge the writer/editors on their assertion that David Crockett owned a slave. I have read many books and articles on Crockett and events in his life but this is the first time I've ever seen that information. There are no footnotes or references and the only "proof" appears to be a mention of the 1820 census and bill of sale. I do not pretend to be a historian or research specialist but I looked at the 1820 census for Lawrence, TN for 1820 and there is a David "Crockit" (different spelling) listed but it doesn't appear to be the same person. On Ancestry.com there is a note that a customer added the possible spelling of "Crockett." I spent several more hours searching the web for supporting information or any "reputable source" and could not find a single one. No biography or autobiography mentions it. I would think the author should prove his allegation or remove it from the book. It diminishes an otherwise solid read. I am open minded to hard proof.
Again, a good overall read but take that one statement "with a grain" of salt.
