I'm so glad you answered. My father also wasn't born in Matanzas, but I was. My greatgrand father was his name was Francisco Tapanes he married Blanca Rosa Diazs also from Matanzas. Francisco Tapanes was orphaned at 16 yrs. He had 7 brothers. I remember some of their names. Virginia was a teacher, Eriberto and tio kuco(Inacio0.
I still have family in Matanzas. My father also told me that all the Tapanes from Matanzas were related one way or another. His cousins used to have a dairy farm at the outskirts of town and he would go has a child.
My greatgrand uncle Eriberto Tapanes married Maria had 2 kidas Eribertico & Racquel. They lived in Matanzas. I remember the story of my fathers cousin who was shot during the revolution Roberto Tapanes. My side of the family was military before Castro.
In 1973 when I came to Miami we saw some of my fathers cousins. His name was or is Rolando Tapanes, he had 2 boys at the time . One was also named Rolando. We also saw Maria Tapanes that lived in California at the time. And her sister Noelia that sang real nice.
I hope this helps some. I still have aunts and uncles Tapanes that I can ask questions Look forward to hearing back from you.
