(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.
English (common in Northumberland and the Scottish Borders): Middle English nickname for someone who was strong in the arm.
Irish: adopted as an English equivalent of Gaelic Ó Labhradha Tréan ‘strong O’Lavery’ or Mac Thréinfhir, literally ‘son of the strong man’, both from Ulster.
FOREBEARS This is a very common surname in North America. It was brought to PA, NJ, and NH in the early 18th century by several different families of northern Irish and northern English Protestants. One such was James Armstrong, who emigrated from Fermanagh to Cumberland Co., PA, in 1745; another was John Armstrong (1720–95), who settled in Carlisle, PA, in about 1748. The Cumberland Valley of PA early became the most concentrated area of Scotch-Irish immigration in America.
