This entitled his father to be addressed as Monsieur le Grand, a style which Charles would later use, after succeeding his father in his posts (at Charles' death, it was given to Louis' grandson, the Prince de Lambesc).
Charles' uncle was the next Duke of Villeroy and the future governor of Louis XV.
His sister, Marie was the mother of Louise Hippolyte Grimaldi, the only Princess of Monaco to reign in her own right.
His older brother Henri, Count of Brionne was expected to succeed to the Armagnac titles but died in 1713, five years before his father.
With his death in 1745,[citation needed] the County of Armagnac reverted to the French king, who had only first given it away to the Guise-Lorrain family in 1645.
