Beatrice was born in Coimbra around the period of 1347–1351. Beatrice's entitlement to be considered an Infanta (Princess) of Portugal is debatable. Some historians consider her a natural daughter of Peter I, so the title Infanta of Portugal could never be attributed to her. Other opinions assert that the death of Inês de Castro was ordered by Peter's father King 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.
