Robert Anderson

(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.

Scottish and northern English: very common patronymic from the personal name Ander(s), a northern Middle English form of Andrew. See also Andreas. The frequency of the surname in Scotland is attributable, at least in part, to the fact that St. Andrew is the patron saint of Scotland, so the personal name has long enjoyed great popularity there. Legend has it that the saint's relics were taken to Scotland in the 4th century by a certain St. Regulus. The surname was brought independently to North America by many different bearers and was particularly common among 18th-century Scotch-Irish settlers in PA and VA. In the United States, it has absorbed many cognate or likesounding names in other European languages, notably Swedish Andersson, Norwegian and Danish Andersen, but also Ukrainian Andreychyn, Hungarian Andrásfi, etc.
