Etienne seems to be the correct officer.
•The French practice in the 18th century of referring to officers by only a single name, which might be a family name or a place from which officer took a title, while some families had several officers in the navy, is the cause of much confusion. I have Conflans and “Perier’s” reports from Archives Nationales, Marine, sous-serie B4, tom 56, but they don’t help; all the references are merely to “M. Perier” and the signature on Perier’s report looks like just “Perier,” no “aîné” or “cadet” and no “Salvert.”
•English accounts can’t be expected to get this right, and French accounts mostly just say “M. Perrier” or “M. Perier” without saying WHICH M. Perier. The official _Gazette_ (I used the Lyon edition for 1744), says the officers involved in capturing _Northumberland_ were “Chevalier de Conflans & … le sieur Perier” (No. 24, June 13, 1744, p. 96). However . . .
•A letter from Brest dated June 5, 1744, refers to “_le Mars_ … commandé par M. Périer l’aîné.” This was published in Adrien Dessalles, _Histoire générale des Antilles_ (Paris: France, Libraire-Éditeur, 1847–48), IV, 599. It seems to have been written by an officer of _Mars_ who would have known which Perier was his captain. The handwritten original is available at the “Gallica” Web site of the Bibliothèque nationale française as “Clairambault 530: Pièces originales du XVIe siècle, pièces diverses,” etc., pp. 247–49 of 321.
•Perhaps on the basis of this letter, Léon Guérin, _Histoire maritime de la France_ (Paris: Dufour et Mulat, 1851), IV, 258, refers to “_le Mars_ … que commandait le capitaine Perier l’aîné.” Guérin seems to have been some kind of unofficial navy historian during the Second Republic and Second Empire; he made extensive use of the navy’s archives when they were first being opened to researchers. Therefore . . .
•On the basis of the June 5 letter and Guérin, I have changed my listing of the commander of _Mars_ during the action with _Northumberland_ from Antoine-Alexis to Etienne.

I have relied on Michel Vergé-Franceschi, _Les officiers généraux de la marine royale (1715–1774)_ (Paris: Librairie de l'Inde, 1990), a massive (7 volumes!) study that focuses on family relationships within the officer corps. Unfortunately, I have the same notes about the _Northumberland_ action on my pages for both Antoine-Alexis and Etienne! Obviously, I was confused at the time I was consulting this work.

The commanding officer of Mars on 1744-05-08 was Capt. Antoine-Alexis Périer (“Périer le cadet," later Périer de Salvert)
