Group A runes were most common in Viking Age Denmark
Alfrun
Old Norse Alfrún (f.)
Alfrún was recorded in West Scandinavia (Norway and Iceland) as a mythological name. It is an Old Norse compound formed from the elements Alf- ‘elf’ and –rún‘confidante’. It has been suggested that when used in a personal name it has the sense of ‘secret, wisdom’, associated with rúnar‘runes’.
There may be one attestation of Alfrún in a medieval church document from Lincolnshire. However, the form may alternatively represent the Old English female personal name, Ælfrūn.
