Robert Leonard

(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 and French (Léonard): from a Germanic personal name composed of the elements leo ‘lion’ (a late addition to the vocabulary of Germanic name elements, taken from Latin) + hard ‘hardy’, ‘brave’, ‘strong’, which was taken to England by the Normans. A saint of this name, who is supposed to have lived in the 6th century, but about whom nothing is known except for a largely fictional life dating from half a millennium later, was popular throughout Europe in the early Middle Ages and was regarded as the patron of peasants and horses.
