Group A runes were most common in Viking Age Denmark
Old Norse Ragni (m.)
Ragni is a short form of names in Ragn-, related to Old Norse regin, genitive plural ragna, ‘ruling powers, the gods’. The personal name element probably has the sense of ‘advice’, but it may indicate ‘the gods’, as it does in Ragnarök, the name of the apocalypse in Old Norse mythology.
A few late instances of the personal name are recorded in West Scandinavia, it is recorded in several runic inscriptions in Sweden. Also, Ragni is the first element of the place-name Ragnall, Nottinghamshire.
