Bibroci
The Bibroci were probably a Celtic ancient people who resided in Britain. They are used by the Roman general and author Gaius Iulius Caesar when describing his second invasion of Britain in 54 BC. BC called De Bello Gallico in his work . He defeated them when he fought against tribes brought together by the British chief Cassivellaunus in the Thames valley, so it can be assumed that the Bibroci also settled in this region.
