Originally a short form of Germanic names beginning with the element beraht meaning "bright, famous". It was borne by the mother of Charlemagne in the 8th century, and it was popularized in England by the Normans. It died out as an English name after the Middle Ages, but was revived in the 19th century. The name also appears in southern Germanic legends (often spelled Perchta or Berchta) belonging to a goddess of animals and weaving.
