Louis de Marillac

He held the office of Marshal of France, as well as lieutenant-general of Trois-Évêchés and governor of Metz.

Louis's mother was Geneviève de Boislevêque, the former widow of a Maître des requêtes.

Louis's elder half-brother from his father's first marriage was Michel de Marillac, who went on to become Superintendent of Finances and Keeper of the Seals.

Due to his dévot position and his support for Marie de Medici and especially Gaston, Duke of Orléans after the Day of Dupes, the king arrested Marillac while he was in Savoy as a military commander at the Mantuan War of Succession.

Despite heavy protests and riots (for Marillac was considered as a very religious and honest man) he was decapitated on 10 May 1632 at the Place de Grève in Paris.
