Born a British subject to an Azorean Portuguese woman (Irene da Silva) and a black Bermudian man known only as "Ruby" at the very height of segregation, Silva emigrated to the United States at the age of five with his mother, eventually acquiring U.S. citizenship by the age of 18 or 19. He adopted the professional name Alan Silva in his twenties.
