Banuelos and Quesada in Huejucar Jalisco

I'm not familiar with the town of Huejucar Jalisco but my Aunt who's family is from there has asked if I could find anything on her families there.
Her parents were Salvador Banuelos and Emma Madrid no dates but approx. 1900 in Huejucar
Salvadors parent Issac Banuelos and Teodora or Todora Flores abt 1875
Teodora Flores's parents were Marcos Flores and Andrea Sandoval married 19 Feb 1867 in Huejucar
Salvadors parents were Santos Banuelos and Leonides Quesada married 20 April 1871 in Huejucar.

I've found children for these parents but no parents for Santos Banuelos or Leonides Quesada. My Aunt was told that Santos father was Francisco Banuelos from Spain but I've found nothing to prove that. Is anyone working any of these lines from Huejucar Jalisco Mexico?

Thanks, Linda in Everett
