 Estors version of Hildebrands origin is much more probable than the legend mentioned above, because Estors arguments are based on a whole library, as is mentioned in the foreword of his "Freiheit ..".In the second volume of his "neue kleine Schriften", pages 195/6, there is a little note, in which Estor says that he had explored the landscapes of Hessen-Darmstadt on horseback or walking to accomplish a book about the national geography of this county.This was in the years around 1730.
