The younger brother of Godefroy, Louis Denis Godefroy, (born in November 1800 in Etain, Meuse), medical student in Toulouse in 1821, then professor at Castres, was presented to the Faculty of Protestant Theology of Montauban (created in 1808 by Napoleon I) and the Protestant consistory named him, on 20 April 1832, pastor in Viane (Tarn) where he will officiate until June 1874. Faithful to family's traditions, Godefroy Calès followed, in Montpellier, the courses at the Faculty of Medicine and was received doctor in 1822. Established in Villefranche-de-Lauragais, where he had early acquired a certain political influence in republican circles, he was named after the Revolution of 1830 Commander of the National Guard; but seeing that the government was embarking on a course which was not his, he resigned. Godefroy remained close, intellectually and politically, to his uncle Jean-Marie, and this, despite the fact that the royalists condemned him to exile and banished him from the national territory in 1816, as a regicide, during the restoration of Monarchy. A letter written from Liège in 1833 by the former conventional and deputy to the Council of the Five-Hundred, and addressed to his nephew Godefroy, explicitly testifies about the proximity of their common republican convictions. Still remaining a member of the Municipal Council of Villefranche until 1848, Godefroy proclaimed that year, during the French second revolution, the Republic, and took over the administration of the city.
