[ADALTRUDIS . Her origin is determined from the charter of "Childebertus rex Francorum" dated 14 Mar 697 which names "Drogus…socer suos…Bercharius…coniuge sui Adaltrute"[337]. On the other hand, the Annales Metenses name "Austrudem filia Warattonis quondam…maioris domus derelictam Bertarii" as wife of "Drogonem primogenitum suum [Pippini]"[338]. The Gesta Fontanellensium also names Adaltrudis, wife of Drogo, as "filia Warattonis [et] Ansfledis coniugis eius"[339], but the 697 charter is probably a more reliable source as, if it is correctly dated, it was written only a few years after the death of Berchar. m (after 688) DROGO dux in Champagne, son of PEPIN "le Gros" maior domus of Austrasia & his first wife Plectrudis (-24 Mar 708, bur Metz, Abbaye de Saint-Arnoul).]
