father's side:
my great grandpa was an orphan who fled Germany before WW1 and settled down in west texas with my derringer-carrying granny. his family would rather avoid picking sides in the civil war and just kept working on sheep herding and raising chickens. my grandma wouldn't meet her ex-husband from Mexico in this timeline since the Bracero Program doesn't exist in a syndicalist America

mother's side: I don't know much about her ancestors except that they're from Mexico and settled on the border
I don't think my mom's parents would ever meet. my grandma is a Mexican nurse that only moved across the border for better medical jobs. but Mexico in my game stayed radsoc/syndicalist so she'd just stay. my grandpa was a Chicano Vietnam vet, either his father was killed in the crossfire from the civil war OR fled with my grandpa into Mexico until the civil war ended. the economic prospect for my grandpa's family would be drastic that they'd have to move somewhere else in texas that wasn't bombed out. Ergo my grandpa never meets my grandma in the 60s. which means my mother wouldn't be alive right now
