It used to be a matter of academic research as to whether or not the Venetti had any connection with Venice. Most say they did not. These place names and ethnonyms "Venice, Vanes, Venedotti, Venetti (Brittany in Gaul), Venetti (by the Adriatic i.e. region of Venice), Venetti (by the Baltic coast), etc., may all reflect common ancestry OR they may all be derived from a common word root.
It has been suggested that word-root in question means "white." It would therefore have been applied to fair peoples who were not necessarily related to each other.
The Venetti in Gaul were described by the Romans as having allies and kinfolk in Britain. A related group is claimed to have settled in Ireland. The Venetti in Gaul had very large formidable ships. They used emblems reminiscent of the Phoenicians (De ROUGEMONT, Frederic. "L'Age de Bronze, ou Les Semites en Occident", Paris, 1866). This whole area of Northern Gaul was once known to the Jews as "Tserefath." Later the term was extended to the whole of France which is its modern usage. The famous commentator Rashi (1040-1105) on Obadiah 1:18, says that the Lost Ten Tribes were to be found in Tserefat meaning he says the land called "Francia" i.e. France.
