Garcia Family of Aguascalientes

My Garcia line ends at 1800 at Don Theodoro Garcia husband of Dionicia de Calvillo. I have a baptism for one of there daughters of whom i descend. I descend from 3-4 of their kids. I need to order the baptism so i can get the line to the 1770's.
I was just really asking who were the first garcias in aguas and are they all related? or different Garcias from los Altos? -Thanks Daniel MdC
