Hello Zenaida,
I am your cousin. Your Dad was Angel, son of Maria Avila and Carmelo Arvelo. My mother's nickname was Chilo (will tell you her real name if I hear from you). My mother was the sister of Angel. They had another sister named Adela and a half brother named Jaime. They all lived in Barrio Hoyo Malo or "El Viente y Cinco" (for Kilometer 25). As far as I know, the only family that remains in that area are the sons of Adela, named Toño and Gilberto (Gilba). They have some sisters living in the US. One is named Rosita and another Judith. I have 4 more brothers that live in Ohio and Arecibo.
God bless you.
Ed
