Alonso Perez Toriello

Many, many years ago i found myself very confused when I read that the genealogist Jaime Holcombe had written that Alonso Pérez toriello was the son of of Diego Rodriguez Herrera and Isabel Hernandez Munoz. According to Jaime Holcombe, Alonso had two brothers named Diego Rodriguez and Francisco Rodriguez. I believe that this was one of the first times that I had dealt with a male using a different surname than his father.

I did much research and learned a lot about surnames in the seventeenth and sixteenth centuries. I also learned that Alonso Perez Toriello was considerered a "foreigner" in nuevagalicia. I connected the Rodriguez Herrera family to a Portuguese/Italian family. Though I had initially found Jaime Holcombe's choice of parents confusing, it made a lot more sense once I had researched this line.

After a few years i realized that most genealogists have Alonso Perez Toriello's parents as Andres Perez and Maria Torillo. What is the source for this information? Where can I find the primary sources that make this claim?

Thanks,
