I was at the Mexican consulate in Austin Texas and I was told that all those that have a "first" name as a last name is from Jewish ancestry.He was an employee at the consulate - but knew - that my family was from the state of Nuevo Leon - good guess - I do not know. Just passing information along. I do not as to it's validity - that is why I am here doing some research. I read all of the postings and have made notes.
Thanks and hope to hear from someone soon as all of the postings are dated as of today.
