Usually the name Judith is from the bible.
But in the older genealogies of the european royalty, Judith also listed in some cases as Juta or Guta, is translated into french or other romance languages as Bona or its equivalant.
Ex. Jean II King of France wife is listed as Bona in some genealogies but in other writen in German, she is listed as Guta or Juta.
