I am searching for my g.grandparents whose names were Ambrosio Salinas and Isabel (dont have her last name). My grandfather, Guillermo Salinas, married my grandmother, Zappopan Riojas, in 1930 in Progreso Coahuila and the marriage certificate states that his parents (Ambrosio and Isabel) were from Candela Coahuila. My grandfather married at 23 years of age. That put his birth year at 1907. Since he was second-to-the-youngest of 6 total children, it indicates that my g grandparents married around 1890-1900 in Candela Coahuila. There's a Candela website and it has a list of all the presidents in the 20th century. I found a Leonardo Salinas Munoz who was president from '43-'45. Don't know if he was from the same Salinas family. Any guidance/information would be appreciated.

Thank you
James
