Group A runes were most common in Viking Age Denmark
Old Norse Ragnhildr (f.)
The female name Ragnhildr is very common throughout the Scandinavian world, including several parts of Britain and Ireland, up to modern times. There is a suggestion that it was restricted to royalty and aristocrats in the Viking Age and then spread to other social groups. It may be the first element of the Lincolnshire place-name Raventhorpe, although in fact the earliest forms suggest the male name Ragnaldr, and more recent publications prefer this interpretation.
