I have been working on the De Luc family for a couple of years now and I have just published an article presenting the family correspondence in the latest issue of the Bulletin de la Société d’Histoire et d’Archéologie de Genève, entitled: Un réseau familial international au XVIIIe siècle : pistes de recherche sur la correspondance privée de Jean-André De Luc. I would like to thank Pr. Christian Grosse from Lausanne University for the opportunity to collaborate to the review, and Gaia Biaggi for the beautiful cartography.
Below is a link to the article (in French), which is to be quoted as follows:
