The request or interest in making A movie, was more than 70 years ago. Older than my mother. Obviously, this wasn't the present day Josey Wales. Her aunt Florence Wilson, I believe, was approached. We do not know from what information the movie would have been made, as it didn't get that far due to the refusal of some of his descendants. Only recently did I learn that part of the family had moved to California and were involved in the movie industry. Did they want to do a movie themselves? Who knows. I appreciate your desire to get to the facts and dismiss all the family lore, however, there may not be the answers you want. As you admit, not much has been recorded about Bill. Alot of it is a mystery and a really good story. Try not to debunk everything.
