She is married to Garcia Sanchez I Of Pamplona.
Andregoto Galíndez was daughter of Count Galindo II Aznárez Count of Aragon from 922, being by his second wife, Sancha Garcés of Pamplona. She is frequently referred to as Countess, and made heiress to her father, yet she was not the eldest daughter of her father, and likewise Aragon had already been absorbed into the Kingdom of Pamplona by Sancho I of Pamplona, years before her marriage to that king's son, García Sánchez I. García, who was her first cousin, divorced Andregoto due to consanguinity, leaving a sole son by her, Sancho II of Pamplona. It has been suggested that Andregoto remarried and had further children, although the details have not been discovered. Endregota, wife of 11th century count Sancho Maceratiz, calls herself a descendant of Andregoto Galíndez, but Ubieto Arteta suggests the later countess descended from her sister Velasquita Galíndez.
