So Blanquillo Marrero married to Eulalia Melendez had a son named Julio Marrero who married Juana Santiago Quilez (my great-grandparents) who I knew well. I had a close bond with her and we called her "Sisa". Julio & Juana "Sisa" had two children; Teresa Marrero (my Mothers Mom) and the singer and composer Raul Marrero who is pretty much the most famous of the Clan loved and respected by all Marreros whether from the Mama Gole branch or Eulalia. He also worked as an actor and had a TV Show here in NYC. The popular song YARE from La Sonora Ponceña was composed by him and the two hits PRIMERO FUI YO and Y COMO LO HACEN made popular by the Tommy Olivencia Orquestra and Frankie Ruiz. Papa Julio was also a composer.
WOW, So no doubt we are cousins! Blanquillo your great grandfather and my great great grandfather. Awesome!
