My great grandmother was Candida Mercado Y Velez. The 1920 U.S. census shows that she was a widow, age 80, living in Barrio Sabana Eneas in San German. Her son was Juan Martinez Y Mercado, age 38, at the time. They worked in the sugar cane fields and the coffee plantations. Any information will help. I do not know if my family moved to other towns or remained in San German.
