- Born: 654, Heristal, Austrasia
- Died: 705, Orp-Le-Grand, Brabant
The Liber Historiæ Francorum records that Pépin had "filium ex alia uxore…Carlo" but does not name the child’s mother. Fredegar (Continuator) records that Pépin married another wife ("aliam duxit uxorem") "nobilem…Chalpaida" by whom he had "filium…Carlo". Sigebert's Vita Landiberto episcopi Traiectensis names "puellam nobilem…Alpaidem" as second wife of Pépin, specifying that she was "soror…Dodonis qui domesticus Pippini principis erat". The mid-12th century Genealogica ex Stirpe Sancti Arnulfi names "Alpade, sorore Dodonis, qui sanctum Lambertum episcopum Leodinensem martyrisavit" as second wife of Pépin. Settipani does not support the theory that Alpais was the sister of Bertrada, mother of Charibert, whose daughter married Pépin King of the Franks, the hypothesis being based on King Pépin and his wife inheriting property from their respective fathers. 1
Alpais married Pépin II "le Gros" NIBELUNG Mayor of the Palace of Austrasia, son of Ansegisel (Anchises) MEROVING Mayor of the Palace in Austrasia and St. Begga DE LANDEN Abbess of Andenne. (Pépin II "le Gros" NIBELUNG Mayor of the Palace of Austrasia was born between 645 and 650 in Heristal, Austrasia, died on 16 Dec 714 in Junille, Meuse, France and was buried in basilique de Saint-Arnoul, Metz.)
