Not likely..as mainstream holds it gets it's name from the ancient
Veniti who lived in the region from the 10th ce. BC forward.
Iow. 1400 years before what you postulate.
If however... your in reference to modernist interpretations of it's early dark age foundings, based on the traditional establishment of the Church of San Giacomo in the year 421 AD...that's a different and more complex debate.
And it includes the hypothesis that neighboring cities towns etc....were under pressure from the Huns and varying Germanic tribes invasions. As to the ethnic diversity of it's population at the time of the latter.... it was probably a polyglot of national groups from the Roman empire to include from the east.
Alas the paucity of sources makes it a difficult question other then plausibility and probability of like cities in the region during the era.
