D'ESMANVILLE, ABBÉ (?–?). The Abbé d'Esmanville was one of three Sulpician priests who accompanied the La Salle expedition to the Gulf of Mexico and landed at Matagorda Bay in Texas in February 1685. The others were René Robert Cavelier, Sieur de La Salle's elder brother, the Abbé Jean Cavelier, and the Abbé Chefdeville. D'Esmanville, like the engineer Minet and several others, returned to France with Capt. Taneguy le Gallois de Beaujeu on the ship Joly, out of disillusionment with the enterprise. The abbé, like La Salle and many of his company, is said to have been from Rouen. His name, although most often written d'Esmanville, says Villiers du Terrage, perhaps should be d'Amonville, as a family living in Rouen in the twentieth century is so called.
