Note: Sources need to be inserted for this profile, as Rothais is not a name of one of Charlemagne's sons that we can find in original sources. His name is cited on other family tree sites too, though. Perhaps the name is incorrect (Charlemagne has a daughter, Rothaide born to Madelgard in 775), or Rothais is a son of Himiltrude after she and Charlemagne split, and was therefore discounted in the main texts on Charlemagne. His birthdate suggests this may be possible, but the fact that Charlemagne's illegitimate children are pretty well documented - and his brother and sister are recorded, makes this less likely. Perhaps he was born to Himiltrude and another partner?
