It derives ultimately from the personal name 'Hrodwulf', itself from the period in history known as The Dark Ages, when names were largely pagan in ancestry, and tended to extoll the undoubted virtues of godliness, strength and purpose. This particular name was composed of the elements "hrod", meaning renown and "wulf", literally the wolf. It may originally have referred to a particular warrior or chieftain. In the Norse language the contracted form was "Hrolfr", and in Danish and Swedish "Rolf", and it was in these forms that they reached Northern Europe in the 8th century. It is not absolutely certain as to the first recording date of the hereditary surname, but it was amongst the earliest of all surnames. Examples taken from authentic rolls and charters of the medieval period include: Johan Rodolfi of Hamburg, Germany, in 1252, Robert Rolf, of Battle, in the county of Sussex, England, in 1272, and Jakob Rufi, given as being a priest in Zurich, Switzerland, in the year 1300. In the church registers of the city of London, England, examples include the marriage of John Roffe and Elizabeth Blythe at St. Stephan's Coleman Street, on November 3rd 1560, and that of Elizabeth Roel and Joseph Cook at St Dunstans in the East, Stepney, on August 5th 1722.Throughout the centuries, surnames in every country have continued to "develop", often leading to astonishing variants of the original spelling.
