i wouldn't know, the merovingian dynasty were the original frankish kings after roman gaul gave way to them in the early 500s, allegedly the line died out with no further heirs, and the carolingian dynasty, founded by pippin took their place. pippin was like the chancellor of the last merovingian king or something like that, he allegedly usurped power back then. it's very old history from a period where there aren't many records or chronicles available to look into the truth of it.
