Louise Marie Madeleine Fontaine
Louise de Fontaine was born in Paris, in the parish of Saint-Roch, on 28 October 1706. Her baptism act was as follows:
Micaela Almonester, Baroness de Pontalba
Louise was the eldest child of wealthy French-Canadian Naval Officer Pierre Denys de La Ronde (1726-1772), reassigned from Nouvelle-France to Nouvelle-Orleans by his Godfather, later French Louisiana Governor, Pierre de Rigaud, Marquis de Vaudreuil-Cavagnial, and later distinguished in the French and Indian Wars. Through her father, Louise was the great-granddaughter of famed Judge and poet René-Louis Chartier de Lotbinière of Maison Lotbinière, a great-great niece of Simon-Pierre Denys de Bonaventure and, through his wife, Charlotte Denys de La Ronde, a great-niece of Claude de Ramezay. Louise's mother, Madeleine (Broutin) Denys de la Ronde, was the daughter of Ignace Francois Broutin, royal engineer, celebrated architect, and commandant of the French militia at Fort Natchez. Her only brother was wealthy plantation owner Pierre Denis de La Ronde (1762 - 1824), who would distinguish himself in the Battle of New Orleans, the Night Attack of which was then fought on his much-admired, if widely misnamed (Versailles, Louisiana), plantation, and beneath its equally misnamed "allée" of Southern live oaks.
