Robert Braun

(male) One of the many French names of Germanic origin that were introduced into Britain by the Normans; it has since remained in continuous use. It is derived from the nearly synonymous elements hrōd ‘fame’ + berht ‘bright, famous’, and had a native Old English predecessor of similar form (Hreodbeorht), which was supplanted by the Norman name. Two dukes of Normandy in the 11th century bore the name: the father of William the Conqueror (sometimes identified with the legendary Robert the Devil), and his eldest son. It was borne also by three kings of Scotland, notably Robert the Bruce (1274–1329), who freed Scotland from English domination. The altered short form Bob is very common, but Hob and Dob, which were common in the Middle Ages and gave rise to surnames, are extinct. See also Rupert.

German and Jewish (Ashkenazic): nickname from German braun ‘brown’ (Middle High German brūn), referring to the color of the hair, complexion, or clothing, or from the personal name Bruno, which was borne by the Dukes of Saxony, among others, from the 10th century or before. It was also the name of several medieval German and Italian saints, including St. Bruno, the founder of the Carthusian order (1030–1101), who was born in Cologne.
