Afonso IV of Portugal
Beatrice was born in 1347 in Coimbra. Beatrice's entitlement to be considered an "Infanta" of Portugal is debatable. Some historians consider her a natural daughter of Peter I, so that title could never be attributed to her. Other opinions assert that the death of Inês de Castro was ordered by Peter's father Afonso IV of Portugal; after inheriting the throne, the Prince admitted that he had married Inês secretly, and she was thus a lawful Queen of Portugal.
