Valladares

Origins.
Valladares (or Valadares in Portuguese and Galician), has its origins in the ancient land of Valadares situated next to Melgaço, the northernmost municipality in Portugal on the south bank of the Minho River which separates Portugal and Galicia. One of the earliest Valadares recorded was the nobleman Soeiro Aires de Valadares, son of Arias Núñez de Valadares and Ximena Núñez, both from Galicia. Soeiro was a member of the "curia regis" of King Alfonso Henriques and appears confirming royal charters from 1169 to 1179. Because of the proximity of northern Portugal and Galicia, the early Valadares can be found on both sides of the border. Soeiro's first wife was Elvira Nunes Velho. He later married Maria Alfonso, an illegitimate daughter of King Alfonso IX of León and his mistress Teresa Gil de Soverosa who had first married Álvaro Fernández de Lara, was later the concubine of her nephew King Alfonso X of Castile and then married as her second husband Suero Arias de Valladares. 
Also a member of this family was Aldonça Lourenço de Valadares, the mother of Ines de Castro.
