Surname is correlated with descent (which is distinct from race, as people understand that word), while in all likelihood the races that were written down for the patients corresponded to the color of their skin, as well as possibly other features. That would suggest three things: First, as you found, there was no correlation between deaths and descent. Presumably there weren't statistically anomalously fewer Gomezes than Smiths. This doesn't eliminate the fact that people wrote down fewer dead as Hispanic than as white. So: Second, there actually were fewer dead Hispanics than dead whites, understanding "Hispanic" as "a person who looks Hispanic" and "white" as "a person who looks white". Third, or alternatively there is no statistical difference between dead Hispanics and dead whites, but somehow fewer dead Hispanics ended up at the morgues to be written down as dead.
