Mendoza family from Paso De Quarenta and Matanzas, Jalisco, Mexico

Hello everyone, my name is David Mendoza. I am looking for any information regarding these two target areas of research concerning the Mendoza family name. My grandfather Ruperto and his brothers and sisters came to the United States over 100 years ago in the early 1900's. Sadly, the history and family relations/ties stayed behind in Mexico. I am hoping to find information to connect myself to the country of my paternal ancestors. I found that my Great-Grandfather was buried in Matanzas, Jalisco, Mexico and that he was married to Rosa Ramirez. On one of his visits to the U.S he scribbled his place of birth as Triumfo, L.C, Mexico? I cannot locate this place to continue my search. Any assistance would be greatly appreciated. Thank you
