SHIPS AND PASSENGER LISTS for Mexico

["yolanda medina-perez" <windrocklili@...>]

Here I go again with the questions but no one that I have spoken to 
has been able to help thus far.  I understand that there were at 
least two ports of entry in Mexico back in the early 1800's, one was 
in Vera Cruz and the other was Tampico. Quien Sabe?  Certainly there 
must have been a trail of paper work MANIFESTS PASSENGER LISTS 
BIRTHS AND DEATHS for the ships. BUT WHERE ARE THEY? I understand 
that there is a site in Spain where passengers would 
register "Indice de las Indias"  How does one go about getting 
information at this site, where do I begin? or is there a place in 
Mexico????
