My grandfathers parents came from Mexico in the early to mid 1900s. My great-grandmother came from Chihuahua, Mexico and my great-grandfather came from Michoacán, Mexico. They worked in a lot of places but mainly stayed in California. My great-grandfather worked in a lot of different jobs and my great-grandmother mainly worked cooking jobs in ranch houses. I don't know exactly when my great-great grandparents from my grandma's side came to the US, probably around the end of the Mexican Revolution, and one of our family relatives worked with/knew Pancho Villa during the Mexican Revolution.
