Help me find my Lopez family line in Zacatecas

I am researching ancestors from Zacatecas and have found several documents from FamilySearch.org. I am stuck on one particular line on my grandmother's side.

If you have any of these people in your family tree, could you please reply to me? And if you do not, but have research tips, could you please reply as well? I am very curious to trace back further generations on this line.

1. Gorgonio Lopez b. about 1845. m. Maria Edurrigis Carrillo (b. 1837 in Zacatecas, Zacatecas, Mexico). d. before 1887.

2. Jose Cruz Lopez b. about 1865 in Jerez, Zacatecas, Mexico about. m. Francisca Rodriguez de los Reyes (b. about 1872 in La Calera, Zacatecas, Mexico) 1887 in Zacatecas, Zacatecas, Mexico. d. before 1909.
3. Maria Paula Lopez b. 1888 in Zacatecas, Zacatecas, Mexico.
3. Maria Margarita Lopez b. 1893 in Zacatecas, Zacatecas, Mexico m. Jose Antunez Perez (b. 1886 San Pedro de Colonias, Coahuila, Mexico) 1909. d. 1979 in Orange, California, USA.
3. Maria Juana Lopez b. 1898 in Zacatecas, Zacatecas, Mexico.

* I believe that Maria Edurrigis Carrillo was remarried to Tranqulino Garcia (b. about 1827) on 20 Jun 1887 in Zacatecas, Zacatecas, Mexico.

I am having difficulty finding death records for everyone in the above line except for my great-grandparents who migrated back and forth from Tijuana to the USA in the 1900s. I am also having difficulty finding records from this time, and I do not know what area in Tijuana they lived in.

I would also like to discover any brothers that the Maria Lopez sisters may have had and other siblings of Jose Cruz Lopez.

Some of the church records are missing in the FamilySearch.org online records, such as La Calera 1872 for Francisca Rodriguez Perez and in Jerez 1865 for Jose Cruz Lopez.

I thank you in advance!
