Segusiavi
From Infogalactic: the planetary knowledge core

A map of Gaul in the 1st century BC, showing the relative positions of the Celtic tribes.
The Segusiavi ("Victorious ones") were a Celtic tribe of Gaul, whose fortress was located at Lugdunum (modern Lyons).[1]
The name "Segusiavi" may have been an alternative name of the "Segobriges" who were legendarily involved with Greeks in pre-Roman Gaul and the foundation myth of Massalia.[2]
