About Albéric de Landen
Albéric de Landen. In an article about his son, St. Gregory of Utrecht, Catholic Encyclopedia says, "[Gregory's] father Alberic was the son of Addula, who, as widow, was Abbess of Pfalzel (Palatiolum) near Trier. On account of the similarity of names, and in consequence of a forged last will, Addula has been frequently confounded with Adala (Adela), daughter of Dagobert II of Austrasia--thus falsely making Gregory a scion of the royal house of the Merovingians."
