All her known roles fall into a 3-year period between 1972-74. There is a flamenco singer of the same name who comes up in Google searches, but I am pretty certain this is not the same person.

- Menudas estrellas (1997 TV series) Ep.: 14.02.1997. IMDb as Mariah Carey. This is a show where celebrities impersonate other celebrities. It is highly unlikely that an actress who hadn't been heard of for 24 years would have appeared as a guest, so I think this credit must refer to someone else of the same name, the flamenco singer maybe.
