Was either of your parents also born in Spain?
Spain — Citizenship by Descent
Spain does not make everyone born on its soil a citizen. Where at least one parent was also born in Spain, the child is Spanish from birth, whatever nationality the parents held — two generations born in Spain is the test. What your parents' nationality was does not matter here; only where they were born.
Yes, at least one of them was born in Spain → No, neither of them was born in Spain → I'm not sure where they were born →
