Pepin (II) of Vermandois, Seigner of St. Quentin and Peronne.
Weis' "Ancestral Roots. . ." (50:16). Count of Senlis, Peronne, and St.
Quentin.

From K.Werner's Die Nachkommen der Karl der Grosse, in volume IV, Karl
der Grosee, ed W.Braunfels, 1965:
"He was living in Italy in until 834 when he went to France to the court
of Louis the Pious. In 840 he was a count in the Paris area, perhaps when
he was among those men faithful to the EMPEROR LOTHAR (RIN 1226) who
tried to stop CHARLES THE BALD (RIN 1620) crossing the Seine."
