The word "Berber" and the element "Brig-" name element are completely unrelated. "Berber" is not only an exonym, it is in fact derived from Greek "Barbaroi" (Βαρβαροι), while Celtic *brig- is from the root *bhr̥gh- ('high', 'exalted', 'powerful'), see also Germanic *burg-. Further, the Berber languages are part of the Afroasiatic language family (related with Ancient Egyptian, the Chadic languages, the Kushitic languages and the Semitic languages). The rest is just dismantlement of superficially similar words.
As regards Tartessian, you should really read this paper by Joseph Eska.![]()
