As the title show, I would be interested to know if there are any records (documents, inscriptions) of the ethnonyms used for the Romanized people (Gallo-Romans, Iberian-Romans, Italics, Rhaeto-Romans) in the first centuries after the fall of the WRE, before the emergence of the current ethnonyms. Further, I would be interested to know what happened with the Roman ethnonym in the centuries following the collapse of the WRE, more exactly, when and how was replaced with the current ethnonyms, like French, Spanish, Italians, Wallon, etc
Thank you in advance
