The family, based in Galicia, achieved an almost unrivalled level of importance in the kingdom of Léon, shown by the fact that between 922 and 1015 no less than four of the kings of León, Ordoño II, Ordoño III, Vermudo II and Alfonso V, married or had relationships with members of the family. Gonzalo Menéndez was a particularly powerful noble during the reign of King Ramiro II, one of the few monarchs with whom the family had no matrimonial connection and with whom Gonzalo came into conflict over the issue of the Viking invasions of Galicia. Gonzalo was created conde by King Vermudo II and was appointed governor of the county of Braga, where he was succeeded by his son Menendo who was the tutor of the young king Alfonso V and, later in life, achieved a level of importance reflected in his being Named as dux de Galicia. His son Ramiro settled in Portugal, but his descendants do not seem to have enjoyed the same status as their more illustrious ancestors.
