Why Didnt He Think About That - Tumblr Posts

So... I watched Coco again and I have a question that keeps bothering me: Did Ernesto de la Cruz have a family?

I mean, if he had a normal family, like a wife and a kid, they're would've been known. But since Miguel thought Rivera were his family, I'm sure he didn't.

He 100% had some nights with ladies, since he's a famous man, so that explains his concern when Miguel "revealed" that he was his grand-grand-grandson. Maybe he thought that one of his one-night ladies could've end up pregnant with his child and passed down the family that fact?

Then why the fact that Miguel, the fourth generation of the family, came to him first? It's understandable that the woman didn't come, there are a hundred of his fangirls, and not everyone's pure hearted, so 100% someone would like about her relationship with the greatest musician.

Ernesto really believed Miguel and was surprised to find out he's Hector's family and not his, but didn't the thought about his possible family concern him? Like why only the 4th generation went to find him ? Why not his kids or grandchildren?
