Although the
Annales D. Alfonsi Portugallensium Regis, record that the wedding of Alfonso and Matilda was celebrated in 1145, it was not until a year later, in May 1146, when they both appear in royal charters. Historian José Mattoso refers to another source,
Noticia sobre a Conquista de Santarém (News on the
Conquest of Santarém), which states that the city was taken on 15 May 1147, less than a year after their marriage. Since at that time no wedding ceremony could be performed during
Lent, Mattoso suggests that the marriage could have taken place in March or April of 1146, possibly on Easter Sunday which fell on 31 March of that year. The groom was almost thirty-eight years old and the bride was about twenty-one years old. The children of this marriage were: • Henry (5 March 1147– June 1155), named after his paternal grandfather,
Henry, he died when he was only eight years old. Despite being just a child he represented his father at a council in
Toledo at the age of three. He died in 1155, shortly after the birth of his brother Sancho. •
Urraca (1148– 1211), married King
Ferdinand II of León and was the mother of King
Alfonso IX. The marriage was subsequently annulled in 1171 or 1172 and she retired in
Zamora, one of the villas that she had received as part of her
arras, and later at the Monastery of Santa María in
Wamba, Valladolid where she was buried.; •
Theresa (1151– 1218),
Countess consort of Flanders due to her marriage to
Philip I and
Duchess consort of Burgundy through her second marriage to
Odo III; •
Mafalda (1153– after 1162). In January 1160, her father and
Ramón Berenguer IV, Count of Barcelona, negotiated the marriage of Mafalda to Alfonso, future King
Alfonso II of Aragon who at that time was three or four years old. After the death of Ramón Berenguer IV in the summer of 1162, King Ferdinand II of León convinced his widow, Queen
Petronilla, to cancel the infante's wedding plans with Mafalda and for Alfonso to marry instead
Sancha, daughter of
Alfonso VII of León and his second wife Queen
Richeza of Poland. Mafalda died in her childhood at an unrecorded date. • Sancho, the future King
Sancho I of Portugal (11 November 1154– 26 March 1211). He was baptised with the name of Martin for having been born on the
saint's feast day.; • John (1156 – 25 August 1164); and • Sancha (1157 – 14 February 1166/67), born ten days before the death of her mother, Sancha died before reaching the age of ten. on 14 February according to the death registry at the Monastery of Santa Cruz (Coimbra) where she was buried. ==Notes==
