Yanez Family Origins

I am new to the forum and researching various family members in Mexico. My question today is around the Yanez family in Nochistlan, Zacatecas. My ancestors include Gonzalo del Monte (circa 1650) and Jose Maria Yanez (circa 1800). I am curious if anyone knows the origins of the Yanez family. Did they come from Spain or Portugal? If anyone has anything they can share, it would be much appreciated. Thanks!
