My great great grandmother was named Constance Auguste, who lived in Laplace in St. John the Baptist Parish. She was a widow according to the 1880 Census where I found her. She had four children, Marie, Elmire and Joseph Phelan whose father was from Ireland and Ida Boutte who was my great grandmother. There were several Auguste's who lived in Laplace or Edgard during that time period, perhaps they migrated to the New Orleans area. If any of this is familiar, please email and share info
