Hey I stumbled upon this post. My paternal side of the family live in Loiza. I don't know much of where we have origiinated. Although, I have been told my great great grandmother was Afro-Carribean. But, as much as I know Loiza was settled by the Spaniards in hopes to profit from sugar canes. With them they imported Nigerian slaves which most escaped and intergrated with the Tainos. I too have always wondered what part of Spain my most of my family have come from. Not to mention I don't get a chance to meet others that are also a Robles. I hope your search goes well. Perhaps this information can be of some interest to you.
