W.H.Turton, "The Plantagenet Ancestry" (Baltimore: Genealogical Publishing
Co., 1968), p. 6, states that Hugues l'Abbi (d. 844) is father of Tertullus
d'Anjou (instead of Conrad of Paris), and that Hughes l`Abbi is a son of
Charlemagne and Regine. Encyclopedia Britannica, 1956 Ed., 1:976:
"...towards 861, Charles the Bald entrusted [the county of Anjou] to Robert
the Strong, but he unfortunately met with his death in 866.... Hugh the
Abbot succeeded him in the countship of Anjou as in most of his other
duties, and on his death (886) it passed to Odo, the eldest son of Robert
the Strong, who, on his accession to the throne of France (888), probably
handed it over to his brother Robert. In any case, during the last years
of the 9th century, in Anjou as elsewhere the power was delegated to a
viscount, Fulk the Red, son of a certain Ingelgerius."
