Thank you so much for what you are doing! I'm looking for my great grandfather Juan Presa Diaz. All I know is that he emigrated to Cuba on a year close to 1900 and married Encarnacion Mas Lorenzo. I know is very vague information but any data on a person named Juan Presa Diaz can help me a lot. Thanks,
Update: I have found out from my family some things about him. He was a coal miner in Tuilla, Langreo, Asturias and traveled to Cuba with his brother Manuel Presa Diaz. I really appreciate if you could help me, I been looking everywhere even familysearch but I can't find anyone with this name.
