The Vazquez/Lopez of Guayama, Puerto Rico

I am currently reseaching the Vazquez/Lopez family tree. It starts in Brooklyn, NY and has led me to Guayama, Puerto Rico. I am trying to find my grandfather, Francisco Vazquez's parents, Juana Bandoni and Felix Vazquez. They were born in Guayama, Puerto Rico. However I do not know their birth dates, marriage date, death date or who their parents were.

Francisco Vazquez' wife was Juanita Lopez. I am researching her father, Juan Lopez also from Guayama, Puerto Rico. I'm also looking for her grandparents.

Any information would be greatly appreciated.
