A relatively old, but fascinating, book about the folklore associated with Louisiana mardi gras, kings, baby dolls, zulus, queens, creoles, cajuns etc is Lyle Saxon, Edward Dreyer and Robert Tallant (Eds and compilers) 'A Collection of Louisiana Folk Tales: Gumbo Ya-Ya' Louisiana Writers Project Publications. The edition that I have was published by Bonanza Books and copyrighted by the Louisiana Library Commission.
