The family are coffee merchants who until recently lived as paupers in Paris. Then they were discovered by Madame la duchesse d’Oyonnax, who as you may know is the cousine of de Gex. She began to serve their coffee exclusively at her salon , and soon enough de Maintenon herself, at her levée, was heard to ask for coffee of this marque, and in no time at all, this family had established a coffeehouse in the village of Versailles, where they serve a steady walk-in trade as well as purveying beans to the royal château and the other estates that abound in this area.
