I recently discovered that the co-author was Joseph Pascal Thueri/Thuery, born April 6, 1757, Ste Anne parish, Montpellier, the son of Marc Thuéry born Jan. 10, 1710 in Moyrazès (Rouergue) from a local family traced back to 1381, and Geneviève Alquier born in Bédarieux, Lodève diocese. He was a clerk at the Commissariat in Montpellier. The local authorities of the First Republic aknowledged his "émigration" on July 26, 1792, but it seems that he actually was working as a clerk at the Highways Dept. (Ponts-et-Chaussées) in Rouen, Normandy. At some point, he slipped back to Montpellier, and was arrested. His trial and immediate execution by guillotine took place on Fructidor 5, second year of the Republic (Aug. 22, 1794) on the Place de la Révolution, formerly known as Place du Peyrou. No need to say, no appeal was possible. He was survived by a few siblings, but this branch of my family disappeared with them. My poor cousin was not very lucky: the tyrant Maximilien de Robespierre and his clique had been beheaded on Thermidor 10, 2nd year (July 28, 1794) in the so-called Réaction Thermidorienne, and the guillotine stopped working shortly after with the new régime known as Directoire, controlled by the very corrupt but humane viscount Paul de Barras.
