Note 1394 — Chapter VII
Reading edition
See Vict. Hist. of ... Norfolk, i, 284-5. I am inclined to think that the Bibroci, whether their name is connected with that of Berkshire or not, and the other two may have lived on the south of the Thames. Otherwise would they not have been clans either of the Trinovantes or the Catuvellauni? It seems unlikely that any group included in the latter would have dared in spite of Cassivellaunus to surrender. Dr. Haverfield (R. L. Poole’s Hist. Atlas of Mod. Europe, 1896, xv,—‘Roman Britain’) suggests that the Bibroci may have been in Berkshire, and that they and the Segontiaci were clans of the Atrebates.
