 Someone named "Seguin" was attested in Frankish chronicles when referring to the Count of Bordeaux and Duke of Vasconia (778, 814 and 816).The name is also recorded in Medieval Latin as "Sihiminus", perhaps a misspelling of "Ximinus", may have been a local Basque whose family later fled south over the Pyrenees and helped Enneco Arista take over in Pamplona.Another character is identified in 778 as ""Jimeno, the strong"", from Arab sources in Al-Andalus, where it calls him ""Mothmin al-Akra"", a Basque or Hispanic magnate in the upper Ebro territories within the later independent principality of Navarre.
