Ligauni
The Ligauni were a Celto-Ligurian tribe dwelling near the Mediterranean coast during the Iron Age and the Roman period. Name 

They are mentioned as Ligaunorumque by Pliny (1st c. AD). A (colonia) in Liga in also attested in the Early Middle Ages (814 AD). The ethnic name Ligauni is probably Celtic, stemming from an earlier *Ligamnī. It has been derived from the root līg- ('to strike'), with Ligauni as 'the beating ones', or from liga- ('mud, sediment, silt'). According to Patrizia de Bernardo Stempel, such linguistically Celtic tribal names suggest that a Celto-Ligurian dialect played an important role among the languages spoken in ancient Ligury. Geography
