I am Manuel Hernandez, the brother of Sergio Hernandez. I have material on the Villalobos-Santoyo family we can share. I also have something, There is a Troncoso-Santoyo relative that died in San Marino, CA a few years ago. This man was the half brother of my mother, Juanita Villalobos. He was born in Lagos in 1922 and immigrated through El Paso. My mom and 2 brothers were born here in California.
