"…Fernando Téllez, Tello Fernández, Fernando Fernández" subscribed the charter dated 1110 under which Queen Urraca granted "las villas de Foramnata y San Estebán en el territorio de Frómista" to "la condes Enderquina". "Tello Fernández dominante La Torre de Monmojon" is named in a charter of Queen Urraca dated 20 Jan 1116. "Enderquina uxor comitis domi Suarii" donated property "in villa…Taliatura…et post obitum porcionem fratris mei Ruderici Guterriz" to Burgos Cathedral by charter dated 4 Mar 1120, witnessed by "de palatio regine et de militibus curie: Xemenus Lupiz maiordomus curie, Rudericus Vermudez, Rudericus Martiniz filius comitis, Tel Fernandiz…Ranemirus filius comitis Froila, comes supradictus Suarius, comes Petrus Gonzaluiz, frater eius Rudericus Gonzaluiz, Petro Lopiz et frater eius Lop Lopez".
Married María, daughter of ---. "Pedro y Orovida Martínez" sold "su heredad en Becerrilejo" to "doña María y a sus hijos Fernando y Gutierre Téllez" by charter dated 7 Apr 1171. "Marina y sus hijos Fernando y Gutierre Téllez" exchanged properties by charter dated 28 May 1172. It is not certain that María/Marina was the widow of Tello Férnandez. If she was the mother of Gutierre Téllez and Urraca Téllez... (and who appear to have been the children of Tello Fernández), she would have been extremely old in 1172. 1
