Three Rè, and three almost unique kings, should be the result of wrong transcriptions of the surname Trerè, which would seem typical of Ravenna, the Italian, Faenza, Conselice and Castel Bolognese, and in Bologna, Imola and medicine, with appearances also in Neapolitan, Trere, absolutely very rare, should be the result of errors in transcription of the previous, which should derive from the Greek name?????? Trères (Treri), name of a Thracian people subjected by the Romans, who became part of the Imperial Byzantine Army, as might also derive from the Byzantine name?????? Trèros (Trero).
