The present bearer of the title is Hereditary Prince Jacques.
The title of "lord of Baux" had been used by other families previously.
King Louis XIII of France re-granted the lordship as a marquisate to Prince Honoré II of Monaco by the Treaty of Péronne on 14 September 1641.
Ercole died before his father, and thus the title has been granted for several centuries to the heirs of the prince of Monaco.
