La indicates that we are dealing with a french name. It would however have been nice if you would say where you had this name from and such which would make this a whole lot easier.
But back to our project. "La" can be translated into "The" "Bron" does not mean anything in French in itself as far as I know. The closest word I can think of is "Brun" which means "Brown".
I knw it has nothing to with this but I just came to remember that in greek "bron" is an onomatipoeticon (sound word) associated with thunder. It is interesting to think that the greeks found that thunder says "Bron Bron".
