I am looking for information on my great grandfather Rafael Fernandez. He was from Asturias, in Spain. He moved to Cuba, where he married Carmen Cienfuegos and had my grandmother, Carmen Piedad Fernandez Cienfuegos in Santiago de las Vegas, Cuba, in 1893. So he had to have arrived in Cuba prior to 1892 or thereabouts.
Does anyone here have any suggstions for how I can track down my Fernandez roots back from Cuba into Spain?
