My grandfather's name was Rosa Marrero from Corozal, PR. He married Ramona Ortiz-Vazquez and had several children. Most of which I believe were given up for 'adoption'. My mom was born in 1941 so I believe they must have been born in the 1920s. Below is a list of some of the siblings.
Rosalia Marrero (my mom)
Raul Marrero (passed away in NY about 4 years ago)
Maria Esther Marrero (in search of)
Juana Marrero (in search of)
