Italians in Mexico

Does anyone know of any books, websites, passenger ship records regarding Italians immigrating to Mexico say during the late 1500's to early 1800's? I've checked out the Archivos Espanoles En Red website: http://aer.mcu.es/sgae/index_aer.jsp to see if I could find my Italian ancestors who settled in Mexico, via Spain, but have come up with a big zero. I have a copy of the book " La Emigracion Castellana y Leonesa al Nuevo Mundo 1517-1700" by Maria del Carmen Martinez Martinez and nothing in there as well.

Rancho del Muerto-12 Feb 2006 Posting Revisited

I was reviewing a 12 Feb 2006 posting regarding Santos Luna's question of the whereabouts of Rancho del Muerto. I did not read it then and apologize for this late response. I ran across what I believe is probably the same rancho referred to as simply "el Muerto" in the margin of a Tepechitlan baptismal manuscript dated 11 Aug 1776. That year Josepha Dominga Luna Miramontes was baptized. The parents were Antonio Miramontes and Victoria de Luna.

Source for Ornelas For those interested

So far my new lost cosuin Stevan and I are researching the Ornelas with detail and trying to find documents proving Alvaro from Lagos de Moreno came from Madeira Islands. I got this from rootsweb. but the link to the actual source appears broken. I will upload the will of Alvaro I later in the week I am busy today!
