Unfortunately, there is very little out there to explore about the life of Catherine Henriette de Balzac d’Entragues, Marquise de Verneuil. She was so reviled during her lifetime for being a greedy mistress with no boundaries or sense of decency, and that reputation has persisted throughout the centuries since the early 1600s. The Chateau de Verneuil, which Henry IV gave to his mistress during their happier days lies mostly in ruins since the days of the Revolution.
