Have you tried the onlibe forms for the registro civil (Gijon - Xixon)? Here is the link https://www.registrocivil.es/info/asturias/gijon/ If you can find where you ancestor was born, you could also determine the local parish and ask for documents. The registro civil goes back only to 1871. Parish records may be in the parish or the diocesan offices. Some civil and parish records were destroyed during the guerra civil.

Hers was the first name I saw on that wonderful list of siblings. I'm not sure they're going to have her digitalized, but you can try online, a the Ministry of Justice, in Madrid, If they ask anythingmore than name and birthdate plus names of parents, which you have, then you will have no choice buttto write to the parish of Quintueles (County villaviciosa).
