Autlán de la Grana

[Gloria Delgado <gloriad@...>]

I'm sure someone in this group has an answer to my question - where 
exactly is  Autlan de la Grana?  Is it near Autlan de Navarro, and are 
both Autlans  part of the larger city?  And how old is Autlan de la 
Grana?  The only thing I can find out from the internet is that it has 
a bullring!
A notebook that belonged to my great-grandparents noted that four of 
their children were born there (ZARAGOZA & CASTILLO surnames).
I'd be grateful for any help or history.
