She married twice, her first husband was Nuño Pérez de Lara who died in 1177 and was the son of Pedro González de Lara and Countess Ava or Eva, the widow of García Ordoñez. His paternal grandparents were Gonzalo Núñez, Lord of Lara and Osma, and Goto Núñez. In WT, he appears as her father which is incorrect and has now been removed as her father and included as her spouse. His father, Pedro, has now been linked to him. A new profile for his mother, Ava, has not been created at this time.
Teresa had six children with Nuño, none of whom have been located in WT and whose profiles have not been created: Fernando Nuñez de Lara, Álvaro Nuñez de Lara, Gonzalo Nuñez de Lara, Sancha Nuñez de Lara, María Nuñez de Lara and Elvira Nuñez de Lara.
In WT Sancho (De Leon) De Leon Del Campo appears as her son with Fernando II. This is incorrect as he was the son of Fernando II with his third and last wife, Urraca López de Haro who should not be confused with his first wife, Urraca de Portugal who appears as his spouse in WT and mother of his firstborn, Alfonso Fernández (Castilla) de León. De_León-193 has been unlinked from Teresa and left as Fernando's son. A new profile for Urraca López de Haro has not been created at this time.
Fernando II and Teresa had two children, Fernando (1178-1187) and an infant, who died the day of his birth with his mother on 06 Feb 1180. They have not been located in WT and new profiles have not been created at this time.
Teresa Alfonso (Castilla), whose CLN, incidentally, should be Alfónsez, is as stated above, De_Lara-22's mother and has been connected to her.
