I am the admin of this website, but also a researcher of Juchipila parish and Juchipila provincia.
A recommendation with all genealogy is to find out what you can from your direct family, i.e. Mother-Father, Aunts-Uncles, Maternal-Paternal grandparents. This will likely establish a baseline of where you may need to focus your research.
When researching in Mexico, it is best to start out with Parish records, if possible. In 1860 Civil records became available, and these are also instrumental in researching Juchipila area families.
A listing of Juchipila Parish records and Juchipila Civil Records that are available are listed in the following link:
Besides the standard, Juchipila baptism, marriage, and death records, the 1844 confirmation records is a very good resource, with many older listed, some dating back to at least the 1780's. These records also provide parentage, due to parish record not being available in the 1700's and early-mide 1800's.
It is recommend to look over the civil records, even if you have a parish record. Sometimes additional info is provided in the civil record that is not available in the parish record and vice-versa.
Besides the typical records noted above, Padrons (Censuses) are invaluable in researching the Juchipila area, with censuses available for 1813, 1819, 1824, and 1841-43. The 1824 and 1841-43 provided ages of household members and is particularly good, if you can no longer find baptism, marriage or death info through the parish or civil records.
Marriage Dispensations are also a valuable resource, often providing Tronco's (genealogy trees) or detailed parentage of ancestors from 2-4 generations back from the year of dispensation. These are especially valubable for the Juchipila area, and are often the only source you may have to link your ancestor back further in time.
There are a number of resources to Marriage dispensations, but the primary source is the diocese of Guadalajara, Jalisco, Mexico, which was responsible for the majority of dispensations in this region.
Some very good genealogists and volunteers have compiled a list on the web, which was created by Claudia Casillas, and here is the link:
The majority of info from the above marriage dispensations is from Latter Day Saint (LDS) Genealogy sources that are available on microfilm/microfiche. These films/fiche recorded the actual records while working with Mexico authorities.
These records have began to be indexed by Ancestry.com which is a genealogy site that requires a member subscription, or available for free at any LDS genealogy library that has a online terminal.
The easiest way I have found to search dispensations via Ancestry so far is to select Mexico (Collection Focus), enter a last name. Enter the keyword: Diócesis de Guadalajara, Guadalajara, Guadalajara, Jalisco, Mexico and in the add event section, select marriage and also place the following again: Diócesis de Guadalajara, Guadalajara, Guadalajara, Jalisco, Mexico
Another area that may help find ancestor connections is Tierra y Aguas (Land/Water) records. They have not yet been indexed online, although there is an index available to search through that does provide names of the key Land/Water owners. This is available at the following link:
Another area that may help find early ancestors is protocols/notories. These mostly include, Wills, Guardianship, Dowry, Mortgage, Land Purchases or Sales, and Agreements/Settlements to disputes.
Guadalajara protocols are available online and have not yet been indexed. It is a huge collection, but hopefully can be indexed some day. It is located at the following Guadalajara Protocols Link:
Another link that includes Zacatecas protocols between about 1614-1668 is the Zacatecas Notorials, which was part of a major project of a Jalisco and Adjacent genealogy group called Nuestro Ranchos. The catalog of Notary Records is from the 17th century, which was found at the State Archives of Zacatecas. The transcriptions were done by Jaime Holcombe and provided to Nuestros Ranchos by Guillermo Tovar de Teresa.
The link for these notaries is:
I am sure there are more sources that I have yet find/access yet, but hopefully this will give the Juchipila research some areas to look at.
