Primeros pobladores españoles en el centro de la Meseta Alteña. Mercedes de tierra en la jurisdicción de Jalostotitlán, 1548-1752. Segunda Edición. (Spanish Edition)

This book has been extremely helpful in my genealogical research with respect to land transfers. It has excerpts of some wills/testaments, land descriptions and lists of previous owners of several properties in Los Altos.

Important information for genealogy.
