Who married Fernando de Aragón (1329-1363)?

El infante Fernando de Aragón (Valencia, 1329-Castellón de la Plana, 16 de julio de 1363) fue hijo del segundo matrimonio de Alfonso IV «el Benigno» con la infanta Leonor de Castilla, hija de Fernando IV de Castilla y de su esposa Constanza de Portugal.

Maria of Portugal (Portuguese pronunciation: [mɐˈɾiɐ]; 6 April 1342, in Évora, Kingdom of Portugal – 1377, in Genoa, Republic of Genoa, Italy) was a Portuguese infanta (princess) member of the House of Burgundy and by marriage Marchioness of Tortosa and Lady of Albarracín.

She was the eldest child and daughter of infante Pedro of Portugal (who became King in 1357) and his first wife Constanza Manuel. Her parents' marriage produced four children, but only infanta Maria and her younger brother, the future King Fernando I of Portugal, survived adulthood; from her father's relationship (or second marriage) with Inês de Castro and later affair with Teresa Lourenço, she had several half-siblings, including Beatriz, Countess consort of Alburquerque and João of Aviz, who became King of Portugal in 1385 and founder of the House of Aviz, who ruled the Kingdom of Portugal until 1580.
