Información Matrimonial: Santiago ALVARES & Librada VELASQUES
Arandas, 1873
In it, Santiago states that he is from Rosa de Castilla and that his mother is Dolores GARCIA.

From what I know, Santiago's direct ascendant line is:
Juan Álvarez del Castillo (tronco)
↘Nicolás Álvarez de Castillo
↘Ramón Álvarez del Castillo
↘Nicolás Álvarez del Castillo
↘Antonio Álvarez del Castillo
↘Juan Manuel Álvarez del Castillo
↘José Vicente Nicolás Álvarez del Castillo
↘Pablo Ygnacio Álvarez
↘Santiago Álvarez=Librada Velásquez

I hope this helps.

¿No será que haya confusión con el apellido? En el rancho Rosa de Castilla en los años 1825 y 1826 hay varios Olibares viviendo allí pero ningún Albares.

Could it be that there is some confusion regarding the family name? In the years 1825 and 1826 there are various individuals with the last name Olibares living in Rosa de Castilla but not a single Albares.

Padron – 1825
