Group A runes were most common in Viking Age Denmark
Old Norse Víkingr (m.)
The male name Víkingr is recorded in some eighteen Viking Age runic inscriptions from Denmark and Sweden, and there is evidence it was used in Norway in the Viking Age and even later. It probably derives from the appellative (common noun) víkingr, the meaning of which varies through time and in the different sources. In Lincolnshire, the place-name Wickenby is formed of either the name or the appellative plus Old Norse -by ‘farm, settlement’.
