The parentage shown here for Gutierre Téllez is attractive because of the connection with Aceca, where his supposed father was killed in battle. According to Salazar y Acha, the Girón family descended from Tello Gutiérrez, who was mayordomo mayor of Alfonso VI King of Castile between 1071 and 1075. However, this appears to be chronologically improbable as he is last mentioned in 1077. Alfonso VIII King of Castile granted "la mitad del castillo y la villa de Aceca" to "don Gutierre Téllez y a su mujer doña Urraca" by charter dated 1 Sep 1166. 1
