Hi, I live in Puerto Rico. There is a man that goes to my church by the name José Kercado (here it is pronounced with an accent and stress on the o). I asked him about Eduardo Kercadó and he says that was his grandfather. José (in his mid 60s) lives in Bayamón, Puerto Rico. He has a great deal of genealogical info on the family, and mentioned that anyone interested can call him at (787)730-5600.
