I have the same confusion as the gal in your office. If they separate race and ethnicity than I’ll check Caucasian for race and Hispanic for ethnicity. If it’s mixed I usually go with White, but I’m not sure which is “correct”.
Many of my great-great grandparents were from Puerto Rico through Spain and the Canary Islands (also Spanish). That would definitely be Hispanic but they never indicate how far back in your lineage they are looking. No indigenous north american though. Me thinks that is her case too. Both are probably correct for us?????
Her parents were both decended from Spaniards.
