Gundoald or Gundovald was a Merovingian usurper king in the area of southern Gaul in either 584 or 585. He claimed to be an illegitimate son of Chlothar I and, with the financial support of the Emperor Maurice, took some major cities in southern Gaul, such as Poitiers and Toulouse, which belonged to Guntram, king of Burgundy, a legitimate son of Chlothar I. Guntram marched against him, calling him nothing more than a miller's son and named him 'Ballomer'. Gundovald fled to Comminges and Guntram's army set down to besiege the citadel. The siege was successful, Gundovald's support drained away quickly and he was handed over by the besieged to be executed.

Saint Gontrand, also called Gontran, Gontram, Guntram, Gunthram, Gunthchramn, and Guntramnus, was the king of the Kingdom of Orléans from AD 561 to AD 592. He was the third-eldest and second-eldest-surviving son of Chlothar I and Ingunda. On his father's death in 561, he became king of a fourth of the Kingdom of the Franks, and made his capital at Orléans. The name "Gontrand" denotes "War Raven".
