A very big thank you to Steven Hernandez for pointing us in the
direction of this website:

http://www.e-local.gob.mx/enciclo.html

the actual home page is: http://www.e-local.gob.mx/

there is a lot of info on Mexico on this site but Zacatecas and
Aguascalientes doesn't seem to be represented on the list of states with
write-ups:

for Jalisco:
http://www.e-local.gob.mx/enciclo/jalisco/

then click on Municipios for a list.

for Chihuahua:
http://www.e-local.gob.mx/enciclo/chihuahua/index.html

then click on Municipios for a list.
