I have a slight problem, though. I'm usually bad at thinking of names for characters, and that's for English names. For Roman and Celtic names, I'm completely lost. If anyone has any ideas, it would be appreciated.
This if from the French Wikipedia. It's a list of known words in ancient Gaulish.
It's what was spoken in Gaul on the continent, but according to the Roman sources the difference between Gaulish and British wasn't very great (Gaulish being closer to british than to other continental Celtic languages)
I have to apoligise to everyone for one veeery long list now... Sorry!
What follows it are some simple rules for how personal names were formed in this language.
Just don't end anybody but royalty's name with "-rix" as it literally means "king" (like the Latin "rex").
I'm afraid I'm leaving for you to get out a French-English dictionary and work out what the words mean in English. (A great learning experience!
