MARTINEZ/MARTIN/ MARTIN DEL CAMPO help Meson de Los sauces/Lagos de Moreno

Hello, so my paternal side is from Meson de Los sauces it seems. As far as I can get any info as most of the recent generations of family was born in Los Angeles, California.
I could find info that my paternal great grand father was actually born in Mexico.
My grandfather is:
Francisco Martinez Hernandez: Born; 7 OCT 1923 Pomona, Los Angeles, California D: 16 FEB 2014 Meson de Los sauces, Encarnacion de diaz, JAL
Celso Martin(ez) Franco: Born ABT: 1901 in Encarnacion de diaz, JAL
He married Maria De Jesus Hernandez: Born ABT: 1903

Celso Martin(ez) Franco’s parents MAY BE:
Francisco Martinez & ildefonsa FRANCO

Maria de Jesus Hernandez parents:
Jose Hernandez: Born ABT: 1875
Gerarda Huerta: Born ABT: 1866 D: 2 September 1949 Encarnacion de diaz, JAL
Marriage was in November 6, 1901 in Encarnacion de diaz JAL.

Any leads will greatly help. I’ve been stuck on this branch for 3 months since I started.
