(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: from a pet form of David.
English: from the Middle English personal name Day(e) or Dey(e), Old English Dæi, apparently from Old English dæg ‘day’, perhaps a short form of Old English personal names such as Dægberht and Dægmund. Reaney, however, points to the Middle English word day(e), dey(e) ‘dairy maid’, ‘(female) servant’ (from Old English dæge, cognate with Old Norse deigja ‘female servant’, ultimately from a root meaning ‘to knead’, and related to the word for dough), which he says came to be used for a servant of either sex.
Irish: Anglicized form of Gaelic Ó Deaghaidh (see O’Dea).
Scottish: from an Anglicized form of the Gaelic personal name Daìdh, a colloquial form of David.
Welsh: from Dai, a pet form of the personal name Dafydd, Welsh form of David.
FOREBEARS This name was brought independently from many parts of Britain to New England by many bearers from the 17th century onward. Robert Day was one of the founders of Hartford, CT, (coming from Cambridge, MA, with Thomas Hooker) in 1635.
