Chronicle of events.  (updated 141018 /extended as time/interest allows)

Initial descriptions provided by the Louisville museum/library honoring John Filson.

Filson's Map -- first of the mysterious wilderness beyond early American civilization, becoming popular in Europe as well, especially in France.  One of those original 9 counties was named Bourbon County, honoring the French Prince who provided men and money to support the westward reach.

While Daniel Boone is better known, this is because of Boone's story as recorded/reported by John Filson whose Map is testamony to Filson's broad travels and expert survey, that finally led to his founding of Cincinnati prior to his questionable demise.

For many years subsequent to Filson's service memorialized in Louisville, there was little acknowledgement of his role in founding Cincinnati, until when the City of Cincinnati graded a flat spot off the summit of Prospect Hill to make a baseball field and swimming pool administered now as Filson Playground by the Recreation Commission.  Apparently, it was deemed the site from which Filson may have obtained the best view of the basin enabling his design of the street grid we enjoy to this day.
