Vellavi
The Vellavi were a Gaulish people in the region of Le Puy-en-Velay in the region of the Auvergne, which, at the time of Julius Caesar's campaigns against the Gaul lay on the border of Gallia Narbonensis. The oppidum of Ruessium, an early seat of a Catholic bishop, began to be called during the 4th century the que dicitur Vetula in pago Vellavorum— the city "called Vetula in the country of the Vellavi" a document of 1004 termed it.Name
The name Vellavi stems from Gaulish vello- attached to the suffix -avus.
The city of Le-Puy-en-Velay, attested as civitas Villavorum ca. 400 CE, and the Velay region, attested as pagus Vellaicus in 845, are named after the Gallic tribe.
