List of Famous people with last name Gascony

William II Sánchez, Duke of Gascony from circa 961 at least until 996, was the younger illegitimate son of duke Sancho IV and successor, around 961, of his childless elder brother, Duke Sancho V. He united the County of Bordeaux with the Gascony. Documents of his reign state that his grandfather came from Iberia, lending credence to "phantasmagorical" genealogies placing the origins of García II Sánchez across the Pyrenees. He died in 996 or 997 and was succeeded by his son, Bernard William.

Odo was Duke of Gascony from 1032 and then Duke of Aquitaine and Count of Poitou from 1038.

Bernard William, sometimes Bernard I, was the Duke of Gascony and Count of Bordeaux from c.997 to his death. During his time, Gascony was effectively independent, its duke a sovereign and any connection to the Kingdom of France theoretical. His reign fell during a period of relative peace and prosperity: the Peace of God movement had originated in Gascony in his father's time, monastic reform was introduced during his reign and the period of Viking attacks was over. Nonetheless, it was also a period of increasing feudal fragmentation, and Bernard died a violent death.

Sancho VI William was the Duke of Gascony from 1009 to his death. His reign is most notable for the renewal of Gascons ties with Spain.

Lupo II is the third-attested historical duke of Gascony, appearing in history for the first time in 769. His ancestry is subject to scholarly debate.
