There was a movie where the grandmother had wind chimes all over her porch/verandah. I think she lived in the Bayou. I had an idea that the girl took up with a carnival worker but it was not Two Moon Junction which I have just watched. Would love to know the name of the movie

Any of these?

Swamp Women (1956) (http://www.imdb.com/title/tt0048682/?ref_=fn_al_tt_1)

The Skeleton Key (2005) (http://www.imdb.com/title/tt0397101/?ref_=nv_sr_1)

Something from American Horror Story (http://www.imdb.com/title/tt1844624/?ref_=nv_sr_1)

Any other details come to mind?
