Jean Baptiste d'Estrehan

Jean-Baptiste d'Estrehan de Beaupré (surname often written as Destrehan; - died 26 February 1765) was a high-ranking French official in colonial Louisiana and the founder of the Destrehan family there. A native of France, he was appointed Royal Treasurer of Louisiana early in the colony's history. He arrived in New Orleans in 1722, the year it was designated as the capital of Louisiana (New France).

Biography D'Estrehan is credited with the completion of the Harvey Canal on the west bank of the Mississippi River in 1739, which connected the river with Barataria Bay to the south and thus to the Gulf of Mexico.

In his role as a colonial official, d'Estrehan clashed with the colonial governor Kerlerec, who described him as being "too rich and dangerous." In France d'Estrehan and the other men were briefly held in the Bastille. They convinced the colonial administration of their view, and Kerlerec was recalled. D'Estrehan returned to New Orleans, where he lived for the remainder of his life.
