In pre-Roman Gaul the Belgic tribe of the Veliocasses or Velocasses controlled a large area in the lower Seine valley, which retains a trace of their name, as the Vexin, in 52 they raised 3000 men to support which son of Celtillus the Avernian, leader of the Gallic tribes?
Vercingetorix Vercingetorix was the son of Celtillus the Avernian, leader of the Gallic tribes. Vercingetorix came to power after his formal designation as chieftain of the Arverni at the oppidum Gergovia in 52 BC. He immediately established an alliance with other Gallic tribes, took command and combined all forces, and led them in the Celts' most significant revolt against Roman power. He won the Battle of Gergovia against Julius Caesar in which several thousands Romans and allies died and Caesar's Roman legions withdrew.
Cinuit of Alt Clut Cinuit (Welsh: "Cynwyd" ) may have been an early ruler of the Brittonic kingdom of Alt Clut, later known as Strathclyde, in Britain's "Hen Ogledd" or "Old North". The Harleian genealogies indicate that he was the son of Ceretic Guletic, who may be identified with the warlord "Ceredig" rebuked by Saint Patrick in one of his letters. According to the same pedigrees, he was the father of Dumnagual Hen, an important but obscure ancestor figure in Welsh tradition. The later genealogy "Bonedd Gwŷr y Gogledd" replaces Cinuit as Dumnagual's father with a certain Idnyuet, said to be the son of Maxen Wledic (the Roman usurper Magnus Maximus). However, the "Bonedd" does include a "Cynwyd Cynwydion" in the ancestry of Clydno Eiddyn, and a Triad attached to the text mentions the "three hundred swords of the (tribe of) Cynwydion" as one of three formidable north British war bands, along with those of Coel Hen and Cynfarch.
