The García de Alba of Jalisco

While researching the ancestry of my fifth great-grandmother Lorenza de Aguilar y García de Alba (born 1740 in Cocula, Jalisco), I discovered that she descended through her maternal line from Francisco García de Alba, who in 1563, was granted land in Ayutla, Jalisco by the second Viceroy of New Spain. According to Jesús Amaya Topete, historian of Ameca, the García de Alba family "flooded" places such as Ahualulco, Ameca, Autlán, Ejutla, and Tecolotlán and Cocula as well. Francisco García de Alba's great-grandson of the same name married Casilda de Ortega Maldonado, who was related to the Topete family of Ameca.

Does anyone also descend from this family?

I'm also trying to look for the book "Ameca, protofundación mexicana", which is the brilliant work of Jesús Amaya Topete, and which contains more information on this family. Does anyone know where I could buy it from?
