Dear Primos,
I've posted my updated GEDCOM, available at:
http://www.nuestrosranchos.org/filemanager/active?fid=3731

It includes primarily information from Jalpa, Tabasco, and Huanusco. The surnames that I've focused on are: Gonzalez, Medina, Sandoval, Viramontes, Casillas, and Ventura.

I've currently hit a brickwall with respect two several individuals: Jose Maria Gonzalez and his wife Petra Ledesma (both probably born around 1770s); and Jose Maria Gonzalez Ledesma, probably born in the 1790s, and Brigida Gonzalez Ledesma, probably born in the 1800s. Petra's father is said to have been Estevan Ledesma and grandfather is Geronimo Ledesma, and I believe Estevan is originally from Tabasco. Jose Maria Gonzalez, Sr and Petra I believe lived in Jalpa. I haven't found their wedding or birth information.

Let me know if you have any questions or if you find any mistakes.

Thanks,
Arturo
