Prairieville Cemetery occupies one of the highest spots in east Ascension Parish and was used to bury those who died during crevasses. About 1785, Joseph Dupuy donated the site as a non-sectarian cemetery, including slaves and Indians. Joseph Dupuy, a bachelor, had these immediate relatives: three sisters, Celeste Dupuy, wife of Leon Duplessis, Mrs. John Parent, and Mrs. Stanislas Braud; and one brother, Trasimond Dupuy.
