I will be spending about three weeks this December and January in 
Jalisco and Zacatecas and am hoping to make it to the parrishes in 
Colotlan and Tlaltenango, perhaps Atolinga as well as the archives in 
Guadalajara...

Question... has anyone ever asked to see the actual books held at the 
parrishes?  I am thinking of asking to photograph some of them, but 
don't know how well that would go over.

Any tips would be appreciated.  I am also going to try to do an 
interview with Esteban Valdes Salazar who has published some very good 
genealogy and history books on Totatiche.  He is the local "cronista" 
and has obviously spent lots of time pouring over old archival 
documents, including the transcription of the 1591 census of Tlaxcaltec 
migrants to Colotlan and the entire 1770 Totatiche census (over 3000 
names).  So if there are any questions anyone would like to ask, please 
let me know.
