"Brutachi qui sunt iudaei " says the chronicle referring to a people north to Caucas -given that Brutos of Brittania was grandson of Askanios son of Aineias called Iuppiter Indiges from the family of Zeus in Troia - easily identifyable with later ashkana-ze jews.
As goths in arian confoederation with jews were also stated to have come from Britain. possibly descendants of Brutos some of whom already living in Germania also came with them to occupy territories of the East,therefore I think the name of jewish Bruder family may go back to this : Brut-Der - meaning Lord Brutos.
