The meaning of Demonbreun
American French: altered form of De Montbrun, a topographic name, with preposition de ‘from’, shortened from the French title sieur de Montbrun, which refers to the placename Montbrun found in various parts of France (e.g. in Aude, Drôme, Lot, and Lozère), presumably in all cases meaning ‘brown mountain’. The surname De Montbrun is found only in Canada, while the surname Demonbreun is most common in TN. History: It was a French Canadian fur trader, Jacques-Timothée Boucher, sieur de Montbrun, whose title was shortened and altered into the surname Demonbreun after he moved to IL in the 1760s and later permanently settled in TN. He was a descendant of Gaspard Boucher, a Frenchman who came to QC in 1635 (see Boucher).
