I am doing research for the Geneology of my Puerto Rican Ancestry. A cousin mentioned that Justino Diaz was the grandson of Altagracia Cuevas Y Rodriguez. She in turn was the sister of my greatgrandmother Maria del Carmen Cuevas Y Rodriguez de Mendoza. They were the daughters of Jose Enrique Cuevas and Isaias Rodriguez, who would be the great grandparents Mr. Diaz and are my great great Grandparents.

I am trying to ascertain the names of mr Diaz's parents. It may provide some clues as to the identities of my third great Grandparents and beyond.

Is this something you can help me with?

Thank you
