Hello Salvador,
My name is Roberto Fernandez, and my mother's father was Juan Jauregui from Zacatecas. My mother was born in Villa de Cos in the the late 1890s. Do you have any information about him since I am trying to build a family tree. Please email me at
robbie1932@earthlink.net. This is the closest I have gotten to a source of information and it is important for me to know. Thank you so much.
