The Charte d'Alaon is a spurious and fraudulent charter purporting to provide a genealogy of the house of Odo the Great, Duke of Aquitaine (715 – 735).
Among the many otherwise unattested claims of the Charte are the descent of the dukes of Aquitaine and Gascony from the Merovingian king Charibert II.
Likewise, the parentage of Lupus II of Gascony is unknown and no relationship between him and the house of Odo or the Merovingians can be proven.
The Jiménez dynasty that ruled Navarre from the 10th through 13th centuries was also purported to descend from one of the sons of Lupus.
"[1] Historian Jules Villain even proposed a connection between the comital dynasties of Comminges and Foix and Lupus II.
