However, the link between the French Catalauni and the British Catuvellauni is not categorically proven: some texts assume they are connected (including, most recently, Graham Robb's "The Ancient Paths"), while others infer a lack of connection from the lack of proof.
Though no actual comparable finds have been made, some parallels have been suggested in representations of similar caps, including a figure of the mythical horse Pegasus on a coin of Tasciovanus, the largely Romanized chief who ruled the Catuvellauni from Verlamion (St Albans) between about 20 BC and 9 AD, and was the father of Cymbeline.
The root uellauno- is found in many other Celtic names, including those of the goddess Icovellauna; the hero Cassivellaunos, later famous in Welsh legend as Caswallawn; and the Catuvellauni, a tribe of southeastern Britain, whose name may also be cognate with Catalauni (Châlons-sur-Marne) and Catalaunia (Catalonia).
In Graham Robb's book "The Ancient Paths" there is a suggestion that Welwyn lay on a late-Celtic highway running in the direction of the summer solstice angle straight from Bury St Edmunds to Salisbury via the Catuvellauni headquarters outside modern-day St Albans.
