Grupo Genealógico Nuestros Ranchos Genealogy Group is for serious genealogists actively searching for lineages in the states of Jalisco, Zacatecas and Aguascalientes of Mexico. The site has recently been relaunched. The Grupo Genealógico Nuestros Ranchos Genealogy Group includes a searchable database of members' GEDCOM files, historical maps, useful research resources and a batch number database of LDS films for the region.
The site appears to mostly be in English although with some messages written in Spanish. You can read them all at: http://www.nuestrosranchos.com.
