Have you looked at the father —
What does he look like???
And the name “Santiago” — what does that sound like??
What is the matter with you - do you lack reading comprehension?
I have not seen photographs of the father. His last name suggests nothing other than that an ancestor was Iberian. He could be any of the.varieties of AfroCaribbean - negro, mulato, mulato claro, mulato-chino, blanco capiro, jabado, etc. from Puerto Rico, Cuba, the D.R. or Venezuela; he could be a Spanish immigrant, he could have been born in Argentina as the great-grandson of a Spaniard and have had a mother of German descent, he could be half-Indian from Ecuador or Guatamala, Honduras,.Mexico,.El Salvador or Peru....he could be a Chicano. The last name in of itself does not inform his racial make up. I know several people with the same Spanish last name who are of different races and from different countries.
