Mexican map site - Jalisco

    Within the last 2-3 months, someone posted a message which included the address of a Mexican governmental website that has online historical maps of various parts of Mexico.  I can't find that site, and, as I recall, when I did visit it, I couldn't find the maps I was looking for.  Specifically, I'm looking for the hacienda/rancho maps of northeast Jalisco near Encarnacion de Diaz, the ranchos southwest of Jerez, Zacatecas, and the rural areas around Durango, Durango.

Can someone please direct me in the right direction?
Thanks.Brenda
