According to her profile on Findagrave.com she was born on October 21st 1906 in Barcelona and she was married to actor Ernesto Vilches (who died in 1954).
Her earliest-known film appearances are in 2 South American productions from the 1940's, one from Chile in 1945 and one from Argentina from 1947 - it would certainly seem likely that there could be more films to be found from this period in her career. She then turned up in Spain, where she appeared in at least 19 films between 1956-61. The last 2 roles listed by IMDb are Mexican productions from 1964 and 1969.
She obviously died at some point, but, perhaps surprisingly, the findagrave site lists no date of death (or grave location for that matter).
