Rolf is a male given name and a surname. It originates in the Germanic name Hrolf, itself a contraction of Hrodwulf (Rudolf), a conjunction of the stem words hrod ("renown") + wulf ("wolf"). The Old Norse cognate is Hrólfr. An alternative but less common variation of Rolf in Norway is Rolv. The oldest evidence of the use of the name Rolf in Sweden is an inscription from the 11th century on a runestone in Forsheda, Småland. https://en.wikipedia.org/wiki/Rolf
