Robert Charles

(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.

French, Welsh, and English: from the French form of the Germanic personal name Carl ‘man’ (which was Latinized as Carolus). In France the personal name was popular from an early date, due to the fame of the Emperor Charlemagne (?742–814; Latin name Carolus Magnus, i.e. Charles the Great). The Old French form Charles was briefly introduced to England by the Normans, but was rare during the main period of surname formation. It was introduced more successfully to Scotland in the 16th century by the Stuarts, who had strong ties with France, and was brought by them to England in the 17th century. Its frequency as a Welsh surname is attributable to the late date of Welsh surname formation. Old English Ceorl ‘peasant’ is also found as a byname, but the resulting Middle English form, Charl, with a patronymic in -s, if it existed at all, would have been absorbed by the French form introduced by the Normans. Compare Carl. English variants pronounced with initial k- for the most part reflect the cognate Old Norse personal name Karl, Karli.
