Louis Césaire Le Breton Deschapelles (1774–1839), planter and public official, was a native of New Orleans who sat for a number of terms on his hometown’s city council between 1803 and 1812. Elected to the newly established state legislature in the latter year, he resigned before taking office. During the War of 1812, Le Breton Deschapelles pledged funds to the war effort and served as a lieutenant in the Louisiana militia. Toward the end of his life he lived on a farm a few miles outside of New Orleans (Maurice Bernard, “Famille Le Bretton des Chapelles,” Généalogie et Histoire de la Caraïbe 64 [1994]: 1163; “Mayors of New Orleans, 1803–1936,” Works Project Administration project 665-64-3-112 [1940 typescript at LN]; Dunbar Rowland, ed., Official Letter Books of W.

Le Breton Deschapelles seems to be referring to the case of Livingston v. D’orgenoy, which had come before the supreme court of the u.s. in February 1813 before being returned to and settled by the district court of louisiana in Edward Livingston’s favor later that same year (Thomas B. Robertson to TJ, 7 Dec. 1810; U.S. Reports description begins Cases Argued and Decided in the Supreme Court of the United States, 1790–  (title varies; originally issued in distinct editions of separately numbered volumes with U.S. Reports volume numbers retroactively assigned; original volume numbers here given parenthetically) description ends , 11 [7 Cranch]: 577–88; William C.
