Family from Arandas

I am looking for my ancestors that lived in Arandas in the 1800's. My grandparents were Francisco Torres & Carmen Torres. "Frank's" parents were Sebastian Torres & Juana Rizo. Carmen's parents were Santiago Torres & Ygnacia Bernal. Santiago & Sebastian were brothers. Their parents were Francisco Torres & Librada Ramires. As far as I could gather, Juana's father was Julian Rizo. Unfortunately Julian was a popular name and more than one kid in the town was named Julian Rizo. I'm having difficulty sorting them out. The Bernals have also been difficult to find. Looks like Exiquiuo Bernal was Ygnacia's dad & Vicenta Velasquez was her mom but that's all I could find. If you can shed some light on on the Rizo and the Bernal family I will be forever grateful.
