"As a subset of all the John Henrys, I would think that a man of the right race, right age in the right place at the right time would be a very small subset, especially given that the population of the area was (at the time) and continues to be small...
"Nicole, I was just responding to what seemed an extraordinarily quick dismissal of this possibly relevant information, and was sensing (perhaps incorrectly) what seemed like an agenda overriding the natural scientific curiousity which I would have anticipated.

I do not rely, for information on the frequency of the name, "John Henry," on the quotation that I gave earlier, from Uncle Beverly Standard. However, Uncle Beverly lived in the Big Bend Community and was speaking largely of "John Henry"'s "of the right race, right age in the right place at the right time."
As I see it, the chances are slim that the particular John Henry for which RB has information is the legendary John Henry. Even so, it remains possible, and every lead that is followed up to some conclusion is a significant contribution to knowledge of the subject, even when the result is negative.
RB should follow his lead, and I would be as pleased as anyone if it should prove out.
