Boxer (1975), p. 66: "The chief exception to this rule of officially discouraging female emigration from Portugal to the East lies in the so-called "Orphans of the King" (Órfãs d'El-Rei), whose numbers Dr. Germano da Silva Correia has investigated so diligently, if often so uncritically. These, as their name implies, were orphan girls of marriageable age, who were sent out in annual batches from orphanages at Lisbon and Oporto (and very occasionally from a few other places such as Coimbra) at the expense of the Crown. They were usually provided with dowries in the form of minor government posts, or with small grants of land, for the men who might marry them after their arrival at Goa.
