That information may be available in an archive in Portugal. But the information that's readily accessible includes neither the birth date nor the home town of Bartolomeu Dias [c. 1450-May 29, 1500]. Dias' two children, Simao and Antonio, had as last names Dias de Novais. Novais is a parish in Vila Nova de Famalicao, which is a municipality in the northern Portuguese district of Braga. So it's possible that Dias, and his ancestors, may have been from Novais. Portuguese historians suggest that both children may have been the offspring of one marriage. But neither the marriage date nor the bride's name is forthcoming. That information may be available through the records of the Catholic Church. For Dias was Catholic. The information won't be available from generations of preserved family history. For Dias' line went extinct with his great granddaughters, Dona Paula de Novais and Dona Violante de Castro, neither of whom married or left behind any known children.
