My father was Jose Antonio Sierra, (Josean) born in SanJuan, Puerto Rico. I understand that his relatives were from Aibonito. His mother's name was Anna Rivera but I know she had previous marriages. I just don't know the details. Anna and my father lived in New York city in the 60's & 70's. He passed away around 1974. I know he had brothers and sisters. The only names I remember are Carmen-Delia, Nilda, Lolin and Domingo. I lost contact with the few relatives I had in the 80's. They probably think I'm dead. Let me know if any of these names rings a bell. Thanks,Tony.
