Robert Lake

(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 (chiefly West Country): topographic name for someone who lived by a stream, Old English lacu, or a habitational name from a place named with this word, for example in Wiltshire and Devon. Modern English lake (Middle English lake) is only distantly related, if at all; it comes via Old French from Latin lacus. This meaning, which ousted the native sense, came too late to be found as a place name element, but may lie behind some examples of the surname.
