I know you posted this several years ago, but in case you are still researching, I was hoping you could share whatever you've found on the Langaricas of Guachinango. My great-grandmother was from Guachinango, Jalisco and her name was Sotera Carrillo Langarica, she married my great-grandfather, Francisco Santiago. My grandfather was Salvador Santiago Carrillo who married my grandmother, Teofila Diaz Perez. I know one of my eldest aunts married a Juan Sanchez.
