Research Notes

This profile was examined in the C-a-T July 2019, using the Report 566 Wikidata - Possible mother,


  • De Lara-22 Teresa Fernández de Traba (De Lara) Child
  • Castilla-61 Teresa Alfonso (Castilla) Possible Mother

Note that new profiles have not been created during the C-a-T; connections have been made among existing profiles only. This notice has been posted in all of the profiles mentioned below.

The child:

  • Teresa Fernández de Traba was the child of Teresa Alfonso and Fernando Pérez de Traba and she has now been connected to both (they are not linked as spouses as they did not marry). Note that her LNAB, De_Lara, is incorrect (it should probably be Traba or Trava).
  • 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.
  • Her second husband was Fernando II de Castilla y León who appears correctly connected to her in WT (no action taken).
  • 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.

His two wives, Berenguela, are probably the same person.
