Robert Stone

(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.

English: from Old English stān ‘stone’, in any of several uses. It is most commonly a topographic name, for someone who lived either on stony ground or by a notable outcrop of rock or a stone boundary-marker or monument, but it is also found as a metonymic occupational name for someone who worked in stone, a mason or stonecutter. There are various places in southern and western England named with this word, for example in Buckinghamshire, Gloucestershire, Hampshire, Kent, Somerset, Staffordshire, and Worcestershire, and the surname may also be a habitational name from any of these.
