(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.
Short forms: Bob, Rob.
Pet forms: Bobby, Robbie, Robin.
Cognates: Irish: Roibéard. Scottish Gaelic: Raibeart. German: Robert, Rupprecht. Dutch: Robrecht, Rob(b)ert. Scandinavian: Robert. French: Robert. Spanish, Portuguese, Italian: Roberto. Czech: Robert. Finnish: Roopertti. Hungarian: Róbert. Latvian: Roberts.
Scottish: 1. habitational name, deriving in most cases from the place so called in Annandale, in Dumfriesshire. This is derived from the genitive case of the personal name John + Middle English tone, toun ‘settlement’ (Old English tūn). There are other places in Scotland so called, including the city of Perth, which used to be known as St. John's Toun, and some of these may also be sources of the surname. 2. variant of Johnson (see John), with intrusive -t-.
FOREBEARS As far as can be ascertained, most Scottish bearers of this surname are descendants of a certain John, probably a Norman baron from England, who held lands at Johnstone in Annandale from the Bruce family in the late 12th century. His son Gilbert was the first to take the surname Johnstone and their descendants later held the earldom of Annandale.
