mother; Berengaria (119827 March 1221), probably the twin sister of Branca, married Valdemar II of Denmark in 1214. Children out of wedlock With Maria Aires de Fornelos, daughter of Aires Nunes de Fornelos and Maior Pais, who was buried at the Monastery of Santo Tirso in accordance with her last will, Sancho had two children, both born before his marriage to Dulce of Aragon: Martim Sanches (born before 1175) Count of Trastámara. Martim married Elo Pérez de Castro, daughter of Pedro Fernández de Castro, with no issue from this marriage; Urraca Sanches (born before 1175), was married to Lourenço Soares, son of Soeiro Viegas and Sancha Bermúdez de Traba.
