Meaning and history
Rolf comes from the Old German name Hrolf, or its Old Norse cognate Hrólfr, a shortened form of Hrodulf (see Rudolf). The Normans brought the name to England, where it quickly became rare, though in modern times it has occasionally been used in the English-speaking world as a German import.
Rolf rose from #925 to #910 for boys between 1965 and 1966. Its highest annual birth count came in 1960, with 96 births.
