 Pepin apparently continued to live at his father's court even after Charlemagne dismissed Pepin's mother Himiltrude to marry Desiderata, the daughter of the Lombard king, around 770.Only after Charlemagne's marriage to Hildegard, and the birth of new male heirs like Charles the Younger (772) and Carloman (773), did Pepin's position seem to become more precarious.In either 780 or 781, Charles had the young Carloman baptized by Pope Hadrian in Rome, renaming him Pepin.
