finding Bustamante

Hi all, I'm going to try this again. I have been trying to locate information on the Bustamante family from Aguascalientes. Cruz was born about 1878, it is called Santa Rosalie on some postings, but his death cert. has aguascalientes. He married Rafaela Garcia where they ended up in El Paso Texas. My question is how do I even find Cruz Bustamante? I can't seem to locate any Bustamantes in Aguas., I can find him on the Pilot program, but want to work with Nuestros. I just can't seem to find any information on them. Cruz might have been a Jr., as I find in my search others, with different birth years. I do know that Rafaela Garcia's family was F. Concepcion Garcia and M. was Cristina Sosa. Any suggestions on how to find them? Any would be a help. Thanks lupe
