You are doing research on your family name of Garza. Did you know that all of the Garzas in the South West, Texas, and Monterrey Mexico come from the Canary Islands and are of Jewish descent. There is a new English book out that deals with the Garza family from the Canary Islands and even has the original Inquisition documents against Alonzo De La Garza. The name of the book is "The Conquistadores and Crypto Jews of Monterey" by David T. Raphael. It is available from www.carmihouse.com
. This book will probably give you a lot of information you did not know. Good Luck!
