What part of me telling you, "hey your family speaks Spanish", changes your character besides maybe the name? It doesn't change appearance, doesn't change personality, doesn't change anything but perhaps the name. But wait, there's something called cultural mixing. Swedish with Hispanic. AfroLatino. Caucasian and Hispanic. Asian and Hispanic. This isn't even hinting on the fact that a family could've just learned or grew up in a place where both English and Spanish are spoken together. Think Expanse Belter language mixing a hodgepodge of languages.
Literally at most, saying your family speaks spanish means that Moran is mixed. Which means, once again, they can have any name. So, no. You're assuming that I'm assuming people should make a Hispanic character. If that was true, I'd just say "Moran is Hispanic" and I'd actually make it a thing. It's not that deep, I promise you.
If that changes how you, as a reader, plays your character go for it. No one is stopping you from playing that path.
And yes, I remember you.
