A bit like Wikipedia, we have tried to draw up the genealogy of the 8 aristocratic dukes of Richelieu. Can anyone find any errors? - the list was surprisingly difficult to create, especially when the line transfers.

The line finally ended in republican 1952 as there was no French monarchy or aristocracy to allow the title to be formally transferred (as in 1657 and 1822).
• These dukes also had the title duc de Fronsac. This subsidiary title - originally awarded to the cardinal himself - was used by the first son of a duke until the decease of his father and his accession to the full ducal title de Richelieu. They used the title of Comte de Chinon, another of the cardinal's subsidiary titles from his ducal estate, for the grandson in his minority (e.g. the 5th duke).
